Two Red Cross workers were killed when their vehicle came under fire from inside a Palestinian refugee camp in Lebanon.
The workers were killed in their vehicle as they tried to escort a Muslim scholar, who has been trying to mediate an end to fighting between the Lebanese army and Fatah Islam militants, out of the Nahr el-Bared camp, the officials said.
The scholar, Sheik Mohammed Haj Ali, was injured in his leg, said the hospital officials from Islamic Hospital in the northern city of Tripoli where the victims were taken. The officials spoke on condition of anonymity, because they were not authorized to speak publicly to the media.
Red Cross officials did not immediately respond to phone calls made by The Associated Press.
Russian officials have repeatedly declared that Israeli aviation poses a threat to the Russian military in Syria.
