The Libyan government has expressed "sadness" over the deaths of two award-winning photographers killed while covering the conflict in Misrata.
But spokesman Moussa Ibrahim said there were always casualties in war, saying: "People die from our side, from their side, people get caught in the middle."
Briton Tim Hetherington and US photographer Chris Hondros were killed in a grenade attack on Wednesday.
Tributes have poured in for the widely respected photo-journalists.
Two other jounalists were injured in the attack, including Briton Guy Martin, a Cornish photographer who was working with Panos Pictures agency. He was hit by shrapnel and is being treated at a hospital in the city.
A survivor told the BBC that a group of journalists had been pulling back from near the front line during a lull in the fighting in Misrata when they were attacked.
