The huge blast at Beirut port has killed at least 137 people, left dozens missing and at least 5,000 wounded, a Lebanese health ministry spokesperson said Thursday.

Tuesday's explosion obliterated part of the port and caused damage over a wide radius in the heart of the city, prompting fears the final death toll could yet rise significantly.
