The attack started when a car was driven over Westminster Bridge hitting and injuring a member of the public also including three Police Officers on their way back from a commendation ceremony. The car then crashed near the parliament and at least one man armed with a knife continued the attack and tried to enter parliament. Sadly i can confirm that now four people have died. That includes the Police Officer who was in parliament, and one man we believed to be an attacker shot by an officer. At least 20 people have been injured. It is long established and well rehearsed friends, parliament has been locked down. That response included uniformed and specialist firearm officers. We now of course have an ongoing operation. What we currently believe, there was only one attacker. Im sure the public will understand they are taking every precaution in locking down and searching the area as thoroughly and exhaustively as possible. I know the officials working in parliament, i thank them for their patience and their support. This investigation has the full weight and expertise of the Terrorism Team behind it. If there are people who saw it that havent spoken to us, do get in touch. The crime scene will remain in place in the affected areas of westminster and we will carry out a painstaking investigation to recover all the possible evidence. Looking forward throughout the rest of the day, including when people are commuting home and in the days that follow, they will see officers on the streets. This includes working longer hours and extra shifts alongside colleagues in the city of london. And, of course, as you are aware we will call forces of military if we need to at a future point. We are asking the bureau to help people worried about friends and family who may have been caught in the attack. We are reaching out to Community Leaders across london to reassure them the strength of the city is to stand together in these terrible times. If anyone sees anything suspicious or that causes concern, please do contact us. Dont hesitate. My thoughts are with all those that have been affected by todays attack and as a service, we lost one of our own as he protected the public and our colleagues. This is the day we plan for and hope it never happens. Sadly it is a reality. We will do all we can to protect the people of london. Ill take a couple of questions. We briefly lost our signal from london, but we have just heard so far the most complete accounting of the chain of events that we are now told caused four deaths and 20 injuries today in london. It began with what they believe is a lone attacker on the Westminster Bridge driving a vehicle into pedestrians and people who are walking along the bridge, then proceeded to parliament, which is at the end of the bridge essentially, tried to storm the grounds, and attacked a Police Officer who was killed. The attacker himself was also killed wounded by police. In all, four people have died, 20 injured. They believe, as i said, it was a lone attacker, but as we heard note in that News Conference, they will act on the assumption it is broader than this and they will take the precaution of searching the area for any other signs of a threat. There you have it, four have died, 20 people injured in this attack in london today. Nbcs kelly is standing by. Kelly, what is the scene like in london right now . Reporter the streets are fairly quiet in this very central part of london. As you can see behind me, this is white hall here. Down over my shoulder is big ben, the houses of parliament in the central area where all of this happened. This area has all been sort of core donned off. The people are gathered around the edges. But you rarely see Central London looking like this. Absolutely empty streets and obviously a vast Police Operation underway right now. As you heard from Scotland Yard, lester, this is an Ongoing Investigation now. They say they believe there is only one attacker, but as a precaution they are searching for any other possible suspect involved in this. This went down more than three hours ago now.

Police investigating a possible terror attack at Westminster Bridge and house of parliament. Well have the very latest from europe after the break. Cle. Hopg tlanhigh pingobs a lot of stujts go to college hoping to land higher paying jobs. Now that Higher Education could come also with a higher price tag. The Cal State Trustees are considering a 5 tuition hike and that has a lot of students feeling angry about the affordability or lack thereof of college. Nbc bay areas pete suratos is live at cal state east bay in hayward. Pete, how are students responding . Do we know what the vote is at this point . Reporter good morning to you, kris. Well, it is spring break here in cal state east bay. Actually at a number of campuses as we speak. Not many students here, but we did speak to one. Well get to that in a moment. But they are streaming this meeting with the board of trustees on their website. I just watched it right now. We know that the finance Committee Just took a vote and they are in favor of this 5 increase, but it is going to go to a vote with the full board later today. Heres some of the video from that meeting that was streaming. Lets explain exactly what this increase would mean. If there is a 5 increase, that means undergraduate tuition would increase just under 300 a year. If youre a graduate student it would increase about 430 a year. Tuition increase proposal had to do with the fact that california governor jerry browns proposed budget in january for the cal state system was about half of what cal state officials expected. Now, it is spring break for students here at cal state east bay, but we were able to find one student and i asked him what he thought about the possibility of a tuition increase. With the cost of living already this high, that increase in tuition is going to be kind of it will cause some students some hardship. Its okay for me just because i do get i get my tuition paid by the va, but for a lot of my friends i dont know if they can afford that extra couple hundred dollars sometimes. Reporter according to members of the board, the funds from the tuition increase would be used to hire more faculty and offer more courses to students and they mentioned Financial Aid will be available to students to cover any increases. If the board approves this increase later this afternoon, it would mark the first increase for the csu state system since 2011. Were live in hayward, pete suratos, nbc bay area news. All right, pete suratos breaking that all down for us. We feel like we have been dodging storm systems left and right and thats going to continue. Thats right. We saw pete earlier today with his hood on. Hes getting rained on now. It looks mild. Kari, the rain isnt over completely. Its not completely over. We could see lingering showers and were drying out as we head into the afternoon. And then we are going to see another round of rain right before the weekend. Heres a live shot looking at emeryville this morning and that slow approach to the bay bridge. But at least we are getting a chance to dry out right here. Its 59 degrees in oakland, 55 degrees in palo alto, and San Francisco at 56 degrees. So, its still fairly cool out there. It will be a cool day back behind the system and some cold air dropping in from the north, a cold front actually passing as we speak. So, its breezy, too, in the sevenday forecast coming up at the bottom of the screen. Were not going to see any really warm days in the forecast until all of this gets out of here. Well start to see those temperatures rebound, but we are looking at how much of that heavy rain we had and over the past 24 hours, most of the bay area had at least a quarter of an inch of rain. There were some spots getting over an inch and over 2 inches in the santa cruz mountains. Well, now we are looking at a lot of that heavy rain moving off towards the east, over parts of the south bay right now, and still some lingering showers as we head through morgan hill and gilroy and san martin. Thats where weve seen some of the heaviest rain moving through this morning. This is a look at the forecast for friday morning. We start out early with that rain in the north bay. It will be moving to the south as we go through that morning commute, early afternoon, still some rounds of rain moving in and some pockets of some heavy downpours. And that will be moving on out, heading into late friday night and Early Saturday Morning with the potential of getting another one to 2 inches of rain. This is what one computer model is showing. We start out with how much rain weve had right now and earlier this morning. And then going to see the potential of getting another inch and a half over the santa cruz mountains. And for the north bay also just about that much. As we get a live look outside right now at kirk wood, if youre heading to the sierra, there is still a Winter Weather advisory and chain controls are up. And we can see why. Its snowing and there will be more snow in the forecast heading into the weekend. High temperatures in the lower 30s. As we get a look at the forecast for yosemite this weekend, it will be in the lower 30s, some off and on snow showers and for the bay area well see more rain.
