Palestinians survey the damage after an Israeli air strike on a Hamas security compound in al-Nuseirat refugee camp in the central Gaza Strip January 12, 2011. Security officials said three air strikes took place around midnight with two missiles slamming into the large Hamas security compound, and an Islamic Jihad training camp and a Hamas naval police station also sustaining hits. There were no reports of any casualties. Palestinian militants have stepped up cross-border rocket attacks on southern Israel in recent weeks and Israel has responded with air strikes.
