At least 30 people are said to have died in Israeli attacks on Gaza on Sunday.
In the northern part of the area, the attacks killed at least 17 people, including women and children, the Gaza Civil Defense Agency said. Thirteen deaths were reported in the southern part of the region, of which at least six were children, according to the authorities.
In recent weeks, Israel has struck the northern part of Gaza controlled by Hamas with enormous force, both from the air and from the ground.
