Injured in the streets, destroyed buildings, cars in Beirut

Massive explosions rocked downtown Beirut on Tuesday, flattening much of the port, damaging buildings and blowing out windows and doors as a giant mushroom cloud rose above the capital.

Witnesses saw many people injured by flying glass and debris.

The cause of the blast was not immediately clear. It came at a time when Lebanon is passing through its worst economic and financial crisis in decades.
