The civil defence agency in Gaza has said three Israeli air strikes killed more than 40 people within an hour across the war-stricken Palestinian territory. Israel said it carried out two of the strikes that civil defence spokesman Mahmud Bassal said killed at least 44 people and left dozens more wounded. The Health Ministry in Gaza said at least 17 people were killed and 26 were wounded close to a petrol station near the southern city of Khan Younis.
