as we head into this holiday weekend. we ve talked to witnesses who were inside this episode this morning. they were told to leave. they were told if you the couldn t shetlter in place some for actually running out of the building. but again, no reports of anyone we could find who actually heard a gunshot. the police presence has not diminished at all over the last hour or so. still investigating this. still a very serious situation here in southeast washington. jeff and of course everybody is very alert when you talk about place where such a tragic mass shooting happened two years ago. stay with us on the scene, jeff. i do want to bring in pamela brown working her sources as always. also jonathan gilliam as well. pamela, let s talk about the 911 call. we ve learned through sources that someone placed a 911 call earlier this morning and said there was a shooting on the
from the white house, pennsylvania avenue outside of the white house does remain closed following the police response to the navy yard this morning. a law enforcement official telling our jim acosta this is standard security precaution in light of any potential incident. not coming from the white house, i was wrong on that. coming from a law enforcement official to jim acosta. pennsylvania avenue remains closed as they assess the situation. let s go to renee marsh. renee what are the capitol police saying? reporter: they re warning people essentially letting people know that has caused them to step up their presence around the capitol ground. they re being proactive because of the reports coming out of this navy yard and the police are now on scene and trying to investigate. they re telling people to realize that stepped up security measures will be visible.
remember, this is the site of where that active shooting was in 2013 that took the lives of 12 people. the huge response under scores the government s terror warnings ahead of this holiday weekend. security has been stepped up. also we re told outside of the white house and also it is being extended for blocks. let s go straight to jeff zeleny on the scene. jeff? reporter: good morning, poppy. you re right. it is still very much an active situation here as you can see. we re on m street southeast in washington, d.c. you can see behind me the navy yard is a couple blocks in the distance. the police presence is as high as it was more than an hour ago when we first arrived on seen. but there s no confirmation that there was a shooter inside. there were just reports of a shooter inside. you can see by the response here how on edge this city is and in fact how on edge the country is
the scene has not been cleared yet, so we can t jump to any conclusions yet. but so far nothing has been found. when you talk about the way security has potentially changed on the base since the 2013 shooting you said fbi is on scene, atf is on scene. also do we know if security at this facility was stepped up since that tragic event in 2013? i know right after the tragic eentd event there was take about that. what i can tell you today, though s that there were various law enforcement agencies that came together and activated the active shooter protocol. there are drills for this. so when this phone call was made that protocol was activated and we saw it play out right here. it s just amazing to see the response here from this 911 call that was made. again, we haven t been able to verify it but still an active situation. jonathan to you. this is a historic facility, the
people. heck the chief of naval operations lives on this base and you have the entire navy jag head quarters on this base. you add to that what happened in 2013. you have to take action. truthfully, what i m seeing right now is perhaps a little bit of over reaction by the civilian police force trying to coordinate the scene and get the right response in place. can you talk to us a little bit about security measures on these bases, how they ve been stepped up in the wake of attacks like the 2013 attack there. yeah. certainly. a few months ago all the military bases in the united states went to force protection level bravo or b. what that means is every single individual was checked as they come onto the base. you have some independent and random searches of vehicles as they come onto the base. you have increased security
