White House placed on security lockdown: Reports

The White House was placed on a security lockdown during the Memorial Day holiday, according to media reports on Monday.

Reuters was not able to confirm the reports. The Secret Service, however, would not allow reporters to leave the White House compound through its western gate and flashing lights from emergency responders could be seen nearby.

Reports state that the White House has been put on a lockdown because of a suspicious package. 

President Barack Obama had visited Arlington Cemetery earlier in the day as part of the annual commemoration for armed services members.

Further details are awaited.
