The mother of Hussein Ahel mourns with one of her children, during her son's funeral in the Daraj area of the central Gaza Strip, Thursday May 22, 2008. Israeli troops opened fire into the crowd of protesters, killing Ahel and wounding 16, including 3 children, a Gaza health official said. At another border crossing earlier on Thursday an Islamic Jihad suicide bomber driving a truck loaded with at least four tons of explosives tried to ram a crucial crossing between Gaza and Israel, militants said, killing himself but causing no other casualties.
