Aftermath of Gaza strikes

Israeli air raids have pounded the Gaza Strip for a third day, hitting key sites linked to militant group Hamas.

Gaza's interior ministry and Islamic University were amongst the latest targets.

Hamas says more than 300 Palestinians have died since Saturday, of which the UN says 57 were civilians. In Israel, a second person was killed by a militant rocket.

Israel has massed forces along the border and has declared the area around the narrow coastal strip a "closed military zone".
