Massive Explosion Rips Through Lebanese Capital Beirut

Beirut, Lebanon: A massive explosion ripped through the Lebanese capital Beirut on Tuesday, injuring many people and blowing out windows in buildings across the city. The source of the explosion was initially believed to be a major fire at a warehouse for firecrackers near the port in Beirut, the state-run National News Agency reported.

The blast sent up a huge mushroom cloud-like shockwave and damaged buildings miles from the port, including the headquarters of former Prime Minister Saad Hariri and CNN's bureau in downtown Beirut.

Lebanese Prime Minister Hassan Diab has confirmed that the blasts took place in a warehouse containing 2,785 tonnes of ammonium nitrate. He said an investigation was under way into how the material had been there for six years.

The Lebanese prime minister has declared a day of mourning today and made it clear that those responsible for the bombing will have to pay the price.
