At least four people were killed in an Israeli strike on a vehicle in Gaza City on Saturday, Palestinian media reported.

The WAFA news agency said the attack occurred in the city's Rimal neighbourhood. Videos circulating on social media showed a charred car with what appeared to be bodies nearby.

An Israeli army spokesman said the incident was under investigation.

Saudi broadcaster Al-Hadath reported that a commander of Hamas' military wing, the al-Qassam Brigades, was killed in the strike, along with his son. Hamas has confirmed the report.

Violence has flared sporadically since a ceasefire between Israel and Hamas came into effect on October 10. Gaza's Hamas-controlled health authority says more than 300 Palestinians have been killed since then.

Since the Gaza war erupted, it says nearly 70,000 people have died in the coastal territory.

The conflict began after Hamas launched a large-scale attack on southern Israel on October 7, 2023, which killed around 1,200 people and saw more than 250 taken to Gaza as hostages.

Hamas in recent days has been accusing the Israeli military of shifting the "yellow line" in Gaza further west. Under the ceasefire agreement, Israeli forces withdrew beyond this line, although they continue to control more than half of the territory.

An Israeli military official said the line had not been moved and is marked with large yellow concrete blocks.
