Israeli war planes launched a series of airstrikes in the Gaza Strip on Tuesday in retaliation for the shooting of an Israeli civilian , killing at least two people, including a three-year old girl, Hamas said.
Palestinian news agency Maan quoted spokesman for the Gaza ministry of health Ashraf al-Qidra as saying that Hala Abu Sbeikha was killed and her mother and brother were injured in an airstrike in al-Maghazi refugee camp .
Maan added that the Israeli air force also raided Hamas sites in south and north of Gaza Strip.It was the heaviest flare-up of violence along the volatile border in months and threatened to destabilize a cease-fire between Israel and Gaza’s Hamas rulers that largely has held for more than a year , according to Associated Press.Israel airstrikes came shortly after a Gaza sniper shot an Israeli civilian laborer  as he performed maintenance work on the border fence. The man was airlifted to a hospital, where he was pronounced dead.The incident occurred as Israeli Prime Minister Benjamin Netanyahu was visiting the nearby town of Sderot , a frequent target of Palestinian attacks, to inaugurate a new rail line.“This is a very severe incident and we will not let it go unanswered,” Netanyahu said. “Our policy until now has been to act beforehand and to respond in force, and this is how we will act regarding this incident as well.”Israel and Hamas are bitter enemies, but both sides largely have observed a cease-fire that ended eight days of heavy fighting in November 2012. The cease-fire has been tested by periodic rocket and mortar attacks out of Gaza . Salafist extremists have been behind most of the violence, but Israel holds Hamas responsible for any attacks out of the territory.
