The Israeli military has launched a new wave of attacks across the Gaza Strip, similar in intensity to the peak of its seven-month war on the besieged Palestinian enclave.

Heavy air strikes were reported across the strip over the weekend and on Monday, with attacks since Friday killing at least 180 Palestinians and wounding dozens more, according to the Palestinian health ministry.

The raids coincided with incursions into Jabalia in northern Gaza, the Zeitoun neighbourhood in Gaza City and eastern Rafah.

The ground advances have been met with fierce resistance by Hamas and other Palestinian groups, with at least five Israeli soldiers killed over the weekend, the Israeli military said.

Another 68 have been wounded over the past 48 hours, including Yogev Bar Sheshet, a brigadier general and deputy defence establishment comptroller, the most senior Israeli officer wounded in the war so far.
