GAZA CITY (AFP) - One Palestinian was killed and seven wounded in at least four overnight Israeli air strikes across the Gaza Strip, Palestinian medics said on Tuesday. The Israeli military said its aircraft had targeted four areas in the Gaza Strip in response to the firing of a Grad rocket from the Palestinian territory into southern Israel. Adham Abu Selmiya, spokesman for the Hamas-run emergency services in the Gaza Strip, said the strikes had killed one Palestinian and wounded seven.
