JERUSALEM (AP) — Incendiary balloons launched from the Gaza Strip on Sunday caused at least three blazes in southern Israel, Israeli media reported, raising the prospect of renewed Israeli strikes on the Hamas-run territory.

Photos and video posted on social media showed Hamas-linked activists launching the balloons. On one of them was written the message: “Time is running out.”

The launches came two months after an 11-day war between Israel and Hamas. The Islamic militant group is upset that Israel has done little to ease a crippling blockade on the territory since the fighting ended, and over delays in indirect negotiations with Israel to resume Qatari financial aid to Gaza.

Israeli media reported at least three fires set in southern Israel, breaking a three-week lull in the launches of the incendiary balloons.

Israel's new prime minister, Naftali Bennett, has compared the balloon launches to rocket fire and has ordered airstrikes following previous launches.
