Palestinian medical officials say an Israeli strike hit a tent sheltering a displaced family in the central Gaza Strip, killing at least three people, including the parents of twins.

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.
