A wounded Hamas policeman guards the destroyed office building of Hamas Prime Minister Ismail Haniyeh after Israeli air strikes in Gaza City November 17, 2012. Israeli aircraft pounded Hamas government buildings in Gaza on Saturday, including the building housing the prime minister’s office, after Israel’s Cabinet authorised the mobilisation of up to 75,000 reservists, preparing the ground for a possible invasion into Gaza.
