(CNN) -- Palestinian militants say they have fired 20 mortar rounds from Gaza into Israel in retaliation for airstrikes that killed one person and wounded 15 others.
The Israel Defense Force said an airstrike Sunday evening targeted two members of a Gaza-based jihad network who were suspected in a June attack that left an Israeli Arab citizen dead.
Two militants and nine civilians, including children, were injured when a rocket hit a motorcycle in Rafah, a town on the Gaza-Egypt border, said Ashraf al-Qidra, a Gaza Health Ministry spokesman. One of those victims died of his wounds Monday.
The IDF, meanwhile, said it targeted terror operations in southern Gaza on Monday following another round of mortars.
The IDF said it responded to the rockets by launching tank shells, though a Health Ministry official in Gaza said it was an airstrike.
Five more people were injured in that operation, the Health Ministry spokesman said Monday.
On the Israeli side, there were no injuries and only minor property damage reported in the barrage, Israeli police spokesman Mickey Rosenfeld said.
