JERUSALEM -- Israel closed the Gaza Strip's offshore fishing zone Sunday following a night of cross-border fighting with Palestinian militants, the most intense escalation of hostilities in recent months.
Palestinian militants in Gaza fired two rockets into southern Israel after Israeli airstrikes targeted sites belonging to the territory's militant Hamas rulers.
The military said the Iron Dome aerial defense system intercepted the two rockets that militants in Gaza launched at southern Israel. But police said rocket fallout caused damage to a house in the town of Sderot, and paramedics treated a 58-year-old man for minor wounds from the exploding glass.
The Israeli army said the strikes were a response to explosive balloons launched by Hamas-affiliated group over the border, and attempts by Palestinian protesters to throw explosives at the Israel-Gaza perimeter fence and soldiers stationed along it.
Dozens of Palestinians took part in the protests. The military said the protesters “burned tires, hurled explosive devices and grenades towards the security fence and attempted to approach it.”
Gaza's Health Ministry said Israeli gunfire at protesters wounded two Palestinians.
Israel holds Hamas, the Islamist militant group ruling the Gaza Strip, responsible for all attacks emanating from the Palestinian territory.
Incendiary balloons from the Gaza Strip have caused damage to Israeli fields in recent days. It comes as Hamas, like other Palestinian factions, denounced the United Arab Emirates for agreeing to formal ties with Israel.
Israeli Defense Minister Benny Gantz ordered the fishing zone off the coast of Gaza closed until further notice in response to the rocket fire.
Following a meeting Sunday with the top army brass, Gantz said in a statement that Israel "will respond forcefully to any violation of sovereignty until complete quiet is restored in the south. If Sderot isn’t quiet, Gaza won’t be either.”
Israel and Egypt have maintained a blockade of the Gaza Strip since Hamas took power in an armed coup in 2007. Israel has fought three wars with Hamas in the Gaza Strip in the years since.
