At least 15 Palestinians were killed and dozens wounded in an Israeli strike on the town of Zawayda in central Gaza, the official Palestinian news agency WAFA reported on Saturday.
The Israeli military is aware of reports of 15 people killed in a Gaza airstrike and is looking into them, a spokesperson said.
Gaza ceasefire talks in Doha paused on Friday with negotiators to meet again next week seeking an agreement to end fighting between Israel and Hamas and free remaining hostages.
Despite the negotiations, Israeli forces on Friday pounded targets across tiny, crowded Gaza and issued new orders for people to leave areas it had previously designated as civilian safe zones, saying Hamas had used them to fire mortars and rockets at Israel.
Israel's military campaign has killed more than 40,000 Palestinians, according to Gaza health authorities.
