At least 20 children are among the dead in attacks north of Beirut and in northern Gaza, officials rescuers and medics say.

DEIR AL-BALAH, Gaza Strip (AP) — Two separate Israeli strikes killed at least 13 people, including women and children, in Gaza on Saturday, Palestinian medical officials said, as Israel announced the first delivery of aid in weeks to war-battered northern Gaza.

Residents said Israeli forces besieged shelters housing displaced families and the remaining population, which some estimated at a few thousand, ordering them to head south through a checkpoint separating two towns and a refugee camp in the north from Gaza City.
