Displaced civilians are fleeing again as Israeli tanks forge deeper into eastern Rafah, reaching some residential districts, stepping up an offensive in the southern border city where more than a million people had been sheltering.
Israel's international allies and aid groups have repeatedly urged against a ground incursion into refugee-packed Rafah, warning of a potential humanitarian catastrophe.
Qatar's Prime Minister Sheikh Mohammed bin Abdulrahman Al-Thani said Israel's operations in Rafah have set back efforts at trying to reach a ceasefire in talks that are being mediated by Qatar and Egypt, although it would continue to negotiate.
Israel has vowed to press on into Rafah even without the support of allies, saying its operation is necessary to root out four remaining Hamas battalions holed up in the city.
"The tanks advanced this morning west of Salahuddin road into the Brzail and Jneina neighbourhoods. They are in the streets inside the built-up area and there are clashes," one resident told Reuters via a chat app.
An unverified video on social media showed one tank on George Street in Al-Jneina neighbourhood.
Hamas's armed wing said it had destroyed an Israeli troop carrier with an Al-Yassin 105 missile in the eastern Al-Salam neighbourhood, killing some crew members and wounding others.
There was no immediate comment by the Israeli military.
Israel issued evacuation orders for people to move from parts of eastern Rafah a week ago, with a second round of orders extending to further zones on Saturday.
They are moving to empty tracts of land, including Al-Mawasi, a sandy strip bordering the coast that Israel has designated as a humanitarian area. Aid agencies have warned the zone lacks sanitary and other facilities to host an influx of displaced people.
UNRWA, the main United Nations aid agency in Gaza, estimates some 450,000 people have fled Rafah since May 6.
