Israeli warplanes bombed the Hamas-ruled Gaza Strip overnight after Palestinians fired a rocket into southern Israel, the army said.
The latest exchange came as Israel warned Hamas it was risking “war” by failing to stop fire balloons being launched across the border.
Egyptian security officials shuttled between the two sides in a bid to end the flare-up which has seen more than a week of rocket and fire balloon attacks from Gaza and nightly Israeli reprisals.
“Earlier tonight, a rocket was fired and during the day, explosive and arson balloons were launched from the Gaza Strip into Israeli territory,” said a military statement released shortly before midnight (2100 GMT).
In response, “fighter jets and (other) aircraft struck additional Hamas military targets in the Gaza Strip.
“During the strike, a military compound belonging to one of the special arrays of the Hamas terror organization was struck,” the English language statement added.
There were no reports from Gaza of casualties.
Israeli President Reuven Rivlin issued a warning to Hamas during a visit to firefighters in the border area who said they were called out to 40 blazes caused by Palestinian arson balloons on Tuesday.
“Terrorism using incendiary kites and balloons is terrorism just like any other,” Rivlin told them, according to a statement from his office.
“Hamas should know that this is not a game. The time will come when they have to decide… If they want war, they will get war,” said Rivlin, whose post is largely ceremonial.
Israel and Hamas have fought three wars since 2008.
