Israeli air strikes hit Gaza as fighting enters second week

Israel killed a senior Palestinian militant commander in Gaza on Monday in air strikes which it said also targeted underground tunnels used by Hamas, and Islamist groups renewed rocket attacks on Israeli cities. The violence entered a second week with no sign of an end to the fiercest hostilities in the region in years, despite growing international concern and mounting calls for a ceasefire. After rockets were fired from Gaza at the Israeli cities of Beersheba and Ashkelon, Israeli jets bombed what the military said were 15 km (nine miles) of underground tunnels used by Hamas.
