The United Nations has said it is “gravely concerned” by Israel’s continued bombardment of the central Gaza Strip and has urged Israeli forces to take all available measures to protect civilians, AFP reports.

The UN Human Rights Office said all attacks had to adhere to international humanitarian law.

“We are gravely concerned about the continued bombardment of Middle Gaza by Israeli forces,” rights office spokesman Seif Magango said in a statement.

“It is particularly concerning that this latest intense bombardment comes after Israeli forces ordered residents from the south of Wadi Gaza to move to Middle Gaza and Tal al-Sultan in Rafah.”
