Amid heavy fighting in Misurata, Libya, Tim Hetherington, producer of the Oscar-nominated film “Restrepo,” was killed by mortar fire Wednesday. Getty photographer Chris Hondros, a Pulitzer Prize finalist, died later in the evening. Michael Brown of the Corvis agency and Guy Martin of the Panos Photo Agency were injured in the same incident. Martin suffered severe injuries, but doctors said his condition was improving.

On Tuesday, Tim Hetherington sent out a last tweet:

Over the last few weeks, Hondros had been filing stunning imagery of the conflict in Libya. One of his photographs appeared on the cover of The Washington Post this morning.

One other foreign journalist has been killed since the start of the conflict in Libya, Al-Jazeera cameraman Ali Hassan al-Jaber died in an ambush near Benghazi on March 12. Four foreign journalists are also still reported missing after being taken into custody on April 5.

Below (all except the last) are images that moved across the wire today, which Hondros captured of the intense fight.
