Washington: A security lockdown at the White House triggered by a loud bang just as President Barack Obama was due to leave was caused by a food vendor cart catching fire on a nearby street, the Secret Service said on Saturday.

Secret Service spokesman Brian Leary said the fire had now been contained and that a vehicle near the White House was being investigated after a bomb-sniffing dog detected something on it.NextMAds
Obama and his family left the White House by motorcade instead of helicopter an hour later and boarded Air Force One at Andrews Air Force Base.
The Obamas are travelling to Selma, Alabama, to commemorate the 50th anniversary of a civil rights march.
Over the past few months, the White House has come under several lockdowns, mostly caused by intruders jumping the fence. Reuters
