Two Afghans have died from their wounds after a grenade attack on a base of the 22-nation peacekeeping force in Kabul in which the attacker also died.
Two French journalists working for the Paris-based NGO Aina were wounded when one or two grenades were thrown on Thursday at Camp Warehouse, one of the main bases of the International Security Assistance Force (ISAF).
The attack was the second in a week targeting foreign troops in Kabul after two U.S. soldiers and their Afghan driver were wounded when grenades were thrown in their jeep on Tuesday.
No ISAF soldiers were hurt on Thursday, but spokesman Major Gordon Mackenzie said an Afghan interpreter working for the force died of wounds on Friday morning.
Aina's director, Marc Victor, told Reuters the French citizens' injuries were not life-threatening, but an Afghan guard from the NGO, Habibullah, 27, who had accompanied them to the base, died of his wounds in hospital on Thursday night.
Eric Coorezits, 27, a cameraman working with Aina's media training programme, suffered a broken leg, while video editor Elsa Leroy, also in her 20s, was slightly wounded in the face. Both work for France Television Channel Three in Grenoble.
"We are fine. We are very lucky to be alive," Leroy said. "We heard a click and then the explosion. I saw the attacker: he looked Afghan and had the grenades in his patu (shawl)."
They will return to France for treatment, she told Reuters. "We are in shock, we don't want to stay. We are too afraid."
ISAF spokesman Colonel Samet Oz told a news briefing the attacker, who had not been identified, had joined a queue of Afghan workers being searched before entering the camp.
Oz said the man threw one or two grenades when he realised he would not get past the checkpoint. One fell about a metre (yard) and a half from him and he was killed outright when a third attached to his waist exploded. Two grenades did not explode.
This week's attacks came after reports from a U.N. group that Osama bin Laden's al Qaeda network had set up several new training camps in eastern Afghanistan near the Pakistani border.
