Israel appears to be readying to send troops into Gaza’s southernmost city of Rafah, the only corner of the strip that has not seen fierce ground fighting and where more than half of the Palestinian territory’s population of 2.3 million has sought shelter.

The Israeli military said on Wednesday that two reservist brigades had been mobilised for missions in Gaza, while video that circulated online appeared to show rows of square white tents going up in Khan Younis, 3 miles (5km) north of Rafah, which was decimated in a months-long Israeli air and ground campaign. A spokesperson for prime minister Benjamin Netanyahu’s government said Israel was “moving ahead” with a ground operation, but gave no timeline.
