Gaza’s civil defence agency says Israeli air strikes have killed at least 33 people, more than half of them children, a day after Israel announced an expanded military campaign, AFP reports.

Civil defence spokesman Mahmud Bassal told AFP that 22 people were killed and at least 100 others wounded in a predawn attack on tents sheltering displaced Palestinians in Al-Mawasi, in the southern Gaza Strip.

Seven people were killed in a strike on a house in northern Gaza’s Jabalia, Bassal said, while the Al-Awda hospital in the same area reported damage. Deaths were also recorded in the cental area of Al-Zawayda and in Khan Younis, in the south, according to Bassal.
