JERUSALEM — Gaza militants fired a barrage of rockets and mortar shells into Israeli territory Monday, causing no casualties but some property damage, after an Israeli airstrike in southern Gaza on Sunday killed one Palestinian and wounded at least nine others.

Israeli warplanes responded immediately, striking a number of rocket-launching squads as they fired toward Israel, according to the military, and hitting several facilities belonging to Hamas, the Islamic group that controls Gaza. The military said the sites were being used to store weapons.
