Israeli forces sent tanks deeper into Khan Younis in the southern Gaza Strip and launched strikes across the enclave as they battled Hamas-led militants, killing at least 34 Palestinians on Wednesday, according to medics.

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. Gaza’s Hamas-run government media office said Abed-Rabbo’s death raised the number of Palestinian journalists killed by Israeli fire to 172 since October 7.

In recent days, Israel has issued several evacuation orders across Gaza, the most since the beginning of the nearly 11-month-old war, prompting an outcry from Palestinians, the UN, and relief officials over the shrinking of humanitarian zones and the absence of safe areas.

The Israeli military said it ordered the evacuation in areas where Hamas and other militants staged attacks, including rocket firing into Israel. The armed wings of Hamas and the Islamic Jihad said fighters were engaged in clashes with Israeli forces in areas across the territory.

More than 40,500 Palestinians have been killed in the war, according to Gaza’s health ministry.
