May 27 (Reuters) - Latest political and security developments in the Palestinian territories and Israel on Sunday:
GAZA - Israel pressed on with air strikes in Gaza, launching five attacks after dark, none causing casualties.
Three aerial assaults were carried out consecutively in northern Gaza, one setting a Hamas executive force position on fire, another destroying a Hamas charity and a third destroying a Hamas force position in Beit Lahiya, Hamas and witnesses said.
Hamas said an Israeli warplane fired a missile at a military command headquarters in southern Gaza earlier, and also struck in an open field to target a rocket crew, Hamas and witnesses said.
An Israeli military spokeswoman confirmed four of the attacks.
There were no reported injuries in any of the Israeli attacks.
SDEROT - Hamas claimed responsibility for firing a rocket that killed a 35-year-old Israeli man, and later a second rocket that slammed into a house in Sderot, damaging it and injuring an Israeli, an Israeli emergency service said.
Since May 15, more than 220 rockets have been launched from Gaza, killing two Israelis and wounding more than a dozen.
Israeli air strikes in Gaza since that time have killed more than 40 Palestinians, most of them militants.
JERUSALEM - Israeli Prime Minister responded to the deadly rocket assault on Sderot by pledging unlimited military action against Hamas, and telling a weekly cabinet meeting that Israel should "be prepared for a long confrontation".
GAZA - Hamas responded to Olmert's threats by formally rejecting a bid by Palestinian President Mahmoud Abbas to renew a truce that would halt rocket fire against the Jewish state in exchange for Israel stopping its air strikes in Gaza.
Hamas spokesman Ayman Taha insisted on an overall truce that would include the West Bank, where Israel conducts frequent raids to arrest suspected militants.
