Israel sent tanks deeper into Jabalia in the northern Gaza Strip and advised people to leave as it pounded the historic Palestinian refugee camp from the air, residents said, Reuters reports.

Palestinian medics said casualties had been reported in Jabalia but that they were unable to reach areas under fire.

Israel’s army has said its forces are trying to stop fighters from the Hamas group staging attacks from Jabalia and want to prevent them regrouping.

“Jabalia is being wiped out,” was repeated in many messages posted on social media by residents of Gaza.

Palestinian health officials did not immediately provide new casualty figures but said dozens had been killed in the Gaza Strip in the past 24 hours. Israel’s military said one soldier had been killed in combat in northern Gaza.

The Israeli army issued new evacuation orders to residents of Jabalia and nearby Beit Hanoun and Beit Lahiya, telling them to head to a humanitarian-designated zone in Al-Mawasi in the southern Gaza Strip.
