A Hamas member was killed in the Gaza Strip on Sunday as he tried to fire a rocket-propelled grenade at nearby Israeli targets, the Israeli Army said. Palestinian hospital officials said the man was critically injured by shrapnel and later died of his wounds at a hospital in the Gaza town of Khan Younis. The man was at the Khan Younis cemetery, near the Jewish settlement of Neve Dekalim, when he hurt himself. In a separate incident, in Gaza City, two Palestinians were hurt in a mysterious explosion. Palestinian police said they were investigating.
