>> all right, richard engel, thank you. here at home, the head of the fbi issued a strong new warning today about an increased terror threat in this country from potential attackers who might be inspired by hamas. garrett haake has that story. >> reporter: on capitol hill tonight, a stark warning about the growing threat at home from the devastating war abroad. >> the ongoing war in the middle east has raised the threat of an attack against americans in the united states to a whole another level. >> reporter: fbi director chris wray signaling the u.s. is in a dangerous period. >> we assess that the actions of hamas and its allies will serve as an inspiration the likes of which we haven't seen since isis. >> reporter: as jewish college students are facing threats on u.s. campuses, cornell university officials today confirming the arrest of a suspect in connection with online threats of a mass shooting and other violence there. >> toe see my own campus targeting one of the buildings, the building i live in, sleep in, it was unbelievable. >> reporter: a las vegas man also charged with threatening to kill nevada senator jacky rosen, who is jewish, after leaving a series of anti-semitic profanity-laced voice mails. >> 3,500 kids dead. >> reporter: also on the hill, anti-war protesters interrupting a hearing as the secretaries of state and defense were pushing the white house plan to spend $105 billion in emergency support for israel, ukraine, and other national security threats. >> ceasefire now! >> reporter: that funding dividing house and senate republicans. new speaker mike johnson setting a vote this week on aid to israel alone, with $14 billion in military and humanitarian assistance. while some gop senators argue to include aid to ukraine. >> to separate the package is naive, because the threats are -- have commonality. >> garrett, what more do the fbi director have to say about the threats here? >> lester, he said the bureau is not tracking any imminent threat from a foreign terrorist group, and that its biggest concern is violent extremists who may be inspired by the events taking place in the middle east. wray urged all americans to continue to be vigilant. lester? >> all right, garrett, the effort under way to get american and other foreign nationals out of gaza is becoming more urgent by the day, but it's uncertain tonight when the vital rafah border crossing from gaza to egypt will be open to more than just humanitarian aid trucks. meagan fitzgerald is there. >> reporter: tonight our firsthand look at the rafah border crossing, a lifeline for millions of people suffering and trapped inside gaza. in the last ten days, more than 200 aid trucks have passed through here, 66 just today. but the u.n. says it's not nearly enough. >> the situation in gaza has become absolutely inhumane. >> reporter: a unicef employee sending this voice message to nbc news from inside gaza, saying the crisis is taking a personal toll on her own daughter. >> i have the youngest, she is 4 years old and she showing symptoms of shows severe symptoms of stress and fear and resores to self-harm like ripping her hair off and scratches kids' eyes until they bleed. >> reporter: unicef warning, a lack of clean water is putting the lives of gaza's one million children at risk of dehydration. the plan was for the rafah border crossing to alleviate this crisis. the rafah border is supposed to be a two-way crossing with these trucks packed with aid making their way in, americans and foreign nationals that are trapped just beyond this border making their way out. but that hasn't happened yet. egypt is not accepting palestinian refugees, and foreign nationals say they have not been allowed out. nearly a thousand americans are trapped inside gaza, and the u.s. says hamas is blocking them. >> the impediment is simple. it's hamas. >> reporter: we pressed egypt's head of state information. who is holding up the americans from crossing over the boarder? >> the americans? >> it's hamas. hamas is holding americans. >> reporter: meanwhile, americans like qasem ali are running out of patience. >> we don't see any care for us from the american government. i don't know why. >> reporter: americans caught in the crossfire, desperate to escape. meagan fitzgerald, nbc news, rafah border crossing, egypt. tonight we are learning much more about concerns raised by family and even members of the military long before an army reservist killed 18 people in maine. emilie ikeda reports now from lewiston, maine. >> reporter: tonight new details on apparent warning signs about the suspect months before the mass shooting. according to records from the county sheriff, robert card's son and ex-wife contacted them on may 3rd, saying they were concerned about his access to firearms because he was hearing voices or starting to experience paranoia. a deputy reached out to card's army reserve unit, who said they would figure out options to get robert help. in july, he spent two weeks in a psychiatric facility. then in september, the army reserve asked for a wellness check on card after he threatened to shoot up their facility. a sergeant was so concerned, he said he thought card could snap and commit a mass shooting. a sheriff's deputy went to card's home twice, but was unable to make contact. a statewide attempt to locate alert was issued. the statewide alert was lifted one week before 18 people were killed. >> they attempted to do two wellness checks but never actually connected with him. should there have been more? >> oh, gosh, follow up until it's done. he wanted to kill somebody. >> reporter: among the victims, his son-in-law josh steele. >> this weekend i was blowing the leaves on my yard. and many times i just stop and break down because this could have been prevented. >> reporter: the army says they determined card should not have a weapon or handle ammunition. while records from the sheriff's office show card's family said they would work to secure his personal guns. at least three guns have been recovered as part of the investigation, all obtained by card legally. maine's governor called for action on monday, but wouldn't say whether law enforcement's response was adequate. >> we want to get the best answer to how can we prevent something like this from happening. that includes why did it happen in the first place. >> reporter: newly released court documents reveal card's sister identified him to police the night of the shooting and told investigators he had been struggling with a bad breakup since the beginning of the year with someone he originally met in a corn hole competition he met at the bar. if your family is trick or treating tonight, beware, we could be on wear for one of the coldest halloweens on record. 77 million are under frost and freeze alerts from texas to new york. some cities like chicago seeing the first snow of the season. and south of minneapolis, multiple crashes reported in slippery conditions. in maui, police have released harrowing previously unseen body cam video showing the response of the lahaina wildfire that killed some 100 people. miguel almaguer has the footage. we have to warn you, some of it may be difficult to watch. >> jesus! you got to go! >> reporter: the heart-pounding video captures a scramble to escape the flames and the race to save lives. >> come out, come out, come out! >> reporter: as wildfires tore through lahaina, maui police rescued 15 people trapped inside a coffee shop on famed front street while thick smoke choked the air and the inferno closed on. >> come on, come on, come on, everybody out, everybody out, everybody out! >> reporter: the harrowing scene unfolding august 8th. this our first perspective from police who selected the 16 minutes of video from 20 hours of footage. >> you say the police department did not do their due diligence to save lives is false. >> reporter: first facing flames at 6:00 in the morning. >> there is a fire. is there anybody else in here? >> reporter: police scrambled to break open locked gates on dirt roads to create escape routes and rush to evacuate residents. >> we're trying to get everybody out! >> reporter: as the blaze erupted through the night, one officer loads a burn victim into his car, realizing he is badly in need of help. >> let's take you straight to the hospital. >> reporter: with 99 believed dead and 2,000 structures destroyed, the 16 minutes of hell are for many a life-time of pain. authorities in maui still have not named a cause for the fire as downed power lines remain a focus of the investigation. lester? >> remarkable video. miguel, thank you. a dramatic scene today in a remote part of a florida everglades where a small plane crashed in the middle of the night. more than seven hours later, rescuers arrived and hoisted the pilot on to a helicopter. he was taken to a hospital with a leg injury. the cause of the crash is being investigated. in 60 seconds, a seat at the table. we speak to families in one city about why what's happening in the middle east is striking such a painful chord with so many american families. this is a search bar. let's know the difference, okay? social media, it can be overwhelming for a young homeowner turning into their parents. what does it mean to slide into someone's dms? -mm. -it sounds like a lot of fun. okay, we're not ready for that. as a team, we'll get there. it might be a fruit emoji, but that doesn't mean they're talking about fruit. -oh. progressive can't save you from becoming your parents, but we can save you money when you bundle home and auto with us. do you really think we need 47 photos of fun dinner at pam's?

>> no. >> reporter: why not? >> because they've been telling for years that they want to destroy not only israel but jews. and people that speak that way you have to believe what they tell you. >> reporter: over lunch, we listened in as three jewish-american opened up about their agony over the war. >> my extended jewish family, friends here, on a daily basis and across the world. and it's terrifying and infuriating. >> i feel like i should keep going back to the word home, and it's not home like a home that's thousands of miles away. it's home that is right here. >> i wish there is a way to have discourse that isn't hateful. there is a way to have a protest that doesn't say kill the jews. >> reporter: and as for the humanitarian concerns in gaza? >> i'm getting very emotional because i really wish there was a way to be able to still see people, but not have it be the enemy that came and slaughtered thousands of our own people. >> reporter: mim's cafe opened nearly a decade ago. palestinian owner of this cafe and his five of children live in the occupied west bank. when you see the images coming out of gaza, of all those casualties, what goes through your head? >> you know, it is horrifying. it is definitely horrifying. >> reporter: we also listened in as palestinian-americans at his restaurant spoke about the war from a much different perspective. >> it does seem clear that israel is geared towards vengeance, not necessarily getting the leadership of hamas by itself. >> until there is an end to israeli occupation and aggression, there will be no peace. >> reporter: they're furious at the u.s. government for not supporting a ceasefire. >> i am honestly not voting democratic again. i'm not going to vote for biden. >> reporter: but for them, this is about much more, what they consider a long history of being dehumanized. >> this idea that we have to constantly earn empathy, it's ridiculous. we're auditions for sympathy. it's outrageous. >> reporter: two tables, two very different viewpoints a world apart. gabe gutierrez, nbc news, minneapolis. we'll take a short break. coming up, with mortgage rates and home prices soaring, how to navigate this tough real estate market. our series "priced out" is next. my name is caron and i'm from brooklyn. i work for the city of new york as a police administrator. i oversee approximately 20 people and my memory just has to be sharp. i always hear people say, you know, when you get older, you know, people lose memory. i didn't want to be that person. i decided to give prevagen a try. my memory became much sharper. i remembered more! i've been taking prevagen for four years now. prevagen. at stores everywhere without a prescription. i'm kareem abdul jabbar. i was diagnosed with afib. the first inkling that something was wrong was i started to notice that i couldn't do things without losing my breath. i couldn't make it through the airport, and every like 20 or 30 yards i had to sit down and get my breath. every physical exertion seemed to exhaust me. and finally, i went to the hospital where i was diagnosed with afib. when i first noticed symptoms, which kept coming and going, i should have gone to the doctor and told them what was happening. instead, i tried to let it pass. if you experience irregular heartbeat, heart racing, chest pain, shortness of breath, fatigue, or light-headedness, you should talk to your doctor. afib increases the risk of stroke about 5 times i want my experience to help others understand the symptoms of atrial fibrillation. when it comes to your health, this is no time to wait. salonpas, makers of powerful pain relief patches for 89 years... believes in continuous improvement... like rounded corners that resist peeling, with an array of active ingredients... and sizes to relieve your pain. salonpas. it's good medicine. as mortgage rates soar with home prices near record highs, what can you do if you're looking for a home in this difficult market? cnbc's diana olick has some answers in our series "priced out." >> reporter: marta moreno is on the hunt for a bigger home. >> that's really cool. >> reporter: but today's sky-high mortgage rates are giving her a big pause. >> i'm guessing you probably have a very low mortgage rate on your current mortgage, yes? >> yes. >> reporter: everybody's got 3%, right? >> yes. it makes it really difficult to purchase a home at a much higher interest rate. >> reporter: in just two years, mortgage rates have gone from 3% to 8%. that adds nearly $1,000 to the monthly payment on today's median-priced home. rates are surging because the federal reserve is still trying to tame inflation, and the economy is still hotter than they'd like. >> we don't know exactly when it's going to be over, but we do hear a chorus of fed speakers in a very notable way saying that they are restrictive and that they can wait and see what happens with the policy filtering through to the economy. >> reporter: high rates are colliding with record low supply of homes for sale, which real estate agents say is freezing the market well before winter hits. >> i think people are anxious, and there is a lot of buyer mentality of we're going to wait and see. >> reporter: if you are one of those buyers, you probably want to get preapproved for a mortgage at a high rate just in case. see if you can pool cash, maybe borrow from family to be more competitive. and be ready to move fast if and when rates drop. so for buyers today, it's a tough call. you can either get in now at a high rate and maybe get a deal on the price, or wait for rates to drop, but then potentially get caught in a wave of competition and end up in a bidding war. lester?
