On Tuesday, a huge explosion rocked the Lebanese capital Beirut shaking buildings and causing a fire in the port district. The blast killed 100 people and injured nearly 4,000 in a toll that officials fear will rise.

Footage of the explosion posted on social media showed a column of smoke rising from the port, followed by an enormous blast, sending a white cloud and a fireball into the sky.
