GAZA CITY, Gaza Strip (AP) — The Israeli military said Palestinian militants in the Gaza Strip fired two rockets into southern Israel late Friday, shattering months of near-total calm. In response, Israeli aircraft attacked two military facilities for Hamas, the Islamic group ruling Gaza. There were no reports of injuries in either incident and no Palestinian militant group immediately claimed responsibility for the rocket attack. The rockets, which hit in opens areas of Israel, were fired a day after Hamas warned of violence over Israeli plans to annex parts of the occupied West Bank. The Israeli military said the airstrikes “will impede” Hamas’ future abilities. Tensions are simmering in the Palestinian territories over Israel’s annexation plans for the West Bank, including the strategically important Jordan Valley. The annexation would effectively dash Palestinian hopes of establishing a viable state in the West Bank, Gaza Strip and east Jerusalem.
