When he first felt the ground shaking, Reuters photographer Mohamed Azakir thought Beirut had been struck by an earthquake.
Then he heard the explosion.
Grabbing his camera, Azakir rushed out into the streets, trying to locate the source of the blast.
Story
Azakir was told by the rescuers that the man was being taken to a hospital. Reuters has not been able to ascertain the identity of the man or to which hospital he was taken.
Beirut's deadliest peace-time explosion was caused after ammonium nitrate being stored near the port ignited. The blast on Tuesday killed at least 145 people, injured 5,000, and left a quarter of a million homeless.
"It was like a horror movie filmed in a devastated city," said Azakir, who has covered Lebanon since 1981.
