The owner of the house, a member of the Islamic Jihad group, was not home at the time. Hashem Asliya said he had been warned to leave the house by the Israeli army shortly before the airstrike. He said his son, Mohammed, suffered a broken leg while jumping out of the house at the time of the attack.
Asliya said: "Even if they killed me and my family, resistance must continue. We will not stop the fight."
About an hour after the attack in northern Gaza, Israeli aircraft struck the home of a Hamas activist in southern Gaza. The man also said that he had been warned ahead of time to leave the premises. No one was injured.
The Israeli army confirmed the airstrikes, saying early on Tuesday that it was targeting arms storage facilities. The army also confirmed that in both cases it had warned residents of the buildings to leave, saying it wanted to avoid civilian causalities.
In the meantime, Egypt deployed 1,300 civilian police officers to beef up security along the Gaza-Egypt border over fears that Palestinian militants might attempt to breach the frontier.
