Israeli forces have sent tanks deeper into Khan Younis in the southern Gaza Strip and launched strikes across the enclave as they battle Hamas, killing at least 34 Palestinians, Reuters reports.

Residents of Khan Younis said Israeli tanks made a surprise advance into the centre of the city, and the military ordered evacuations in the east, forcing many families to run for safety, while others were trapped at home.

Palestinian health officials said the Israeli strikes in Khan Younis killed at least 11 people.

In the central city of Deir Al-Balah, where at least a million people were sheltering, an Israeli airstrike killed eight Palestinians near a school housing displaced families, medics said.

In Nuseirat, in the central Gaza Strip, journalist Mohammed Abed-Rabbo was killed along with his sister in an Israeli attack on their house, medics said.
