Palestinian officials say that at least 11 people have been injured by Israeli air strikes targeting Gaza's airport. The Israeli military confirmed the missile strikes near Rafah in southern Gaza which, it said, targeted militants. It was the second night of Israeli raids since a rocket fired from the Gaza Strip killed a worker on an Israeli farm on Thursday.Earlier, the international Middle East Quartet called for Israel to freeze all settlements in Palestinian territories. In a strongly worded statement, the Quartet condemned Israel's announcement last week of planning permission for 1,600 new homes in East Jerusalem occupied by Israel since 1967.Yesterday's missiles hit Gaza's long disused international airport and tunnels dug by militants near the border with Israel. On Thursday, Israeli missiles hit smuggling tunnels and a metal workshop in Gaza but there were no reports of serious injuries. An Israeli military spokesman said the strikes were a response to five rockets fired at Israel from Gaza in the past two days including one that killed a farm worker from Thailand in a kibbutz in southern Israel.
