GAZA CITY (AFP) - Seven people were wounded in Gaza on Sunday by what Palestinian medical sources said was an Israeli air strike, but Israel denied it had carried out any such raid. Adham Abu Selmiya, spokesman for the Hamas-run medical services in the Gaza Strip, said four children and three adults suffered moderate injuries in air strikes in the northern Beit Hanun area. But a spokeswoman for the Israel Defence Forces told AFP "there was no IDF activity in Gaza overnight or this morning." The reported raid comes after days of rocket fire from Gaza into southern Israel and four straight days of retaliatory Israeli air strikes between Tuesday and Friday night.
