New Delhi, Nov. 29 -- Israeli forces on Thursday killed a pair of Palestinian men in the occupied West Bank after they appeared to surrender to troops, drawing Palestinian accusations that the men were executed "in cold blood." The Israeli military said it was investigating.

The killings, captured in videos shown on two Arab TV stations, came as Israel pressed ahead with its latest offensive in the West Bank, where the army has stepped up its activities over the past two years. Israel says it is cracking down on militants, but Palestinians and rights groups accuse Israel of using excessive force and say dozens of unarmed civilians have been killed.
