JERUSALEM—Israel's military says its aircraft fired at militants belonging to an al-Qaida-inspired group in Gaza a day after rockets hit a house in Israel.

A military statement said aircraft "targeted terror operatives" of a "Gaza-based global jihad affiliate" Saturday evening.

Palestinian health official Ashraf al-Kidra said one man was killed and another injured in the airstrike. Hamas said a security facility was hit, causing no injuries.

A rocket fired from Gaza hit a house in southern Israel on Friday. Nobody was hurt but a bedroom was sprayed with shrapnel.

Israel and Gaza's Hamas rulers have mostly kept an unwritten truce since a short war almost four years ago. Attacks have persisted but at a slower pace. Gaza militants fired over 40 rockets at Israeli towns this month, the military said.
