Smoke from a fire near the border between Israel and the Gaza Strip is seen from the Israeli town of Sderot.
The cause of the fire and its exact location are not clear.
It comes on the third day of a four-day truce between Israel and Hamas.
Hamas's October 7 attack sparked an air and ground offensive by Israel, which has vowed to destroy the Palestinian militants.
In Gaza, nearly 15,000 people have been killed in the war, officials in the Hamas-run territory said.
About 1,200 people, mostly civilians, were killed in Israel during the October 7 attack and around 240 taken hostage, according to Israeli officials.
