in a further test of a fragile ceasefire between the Palestinian militant group Hamas and Israel. Witnesses and medics said the first attack hit a car in the densely populated Rimal neighborhood, setting it ablaze. It was not immediately clear whether the five dead were passengers of the car or included passersby. Dozens of people rushed to extinguish the fire and rescue the victims. Shortly after the attack on the car, the Israeli air force carried out two separate airstrikes on two houses in Deir Al-Balah city and Nuseirat camp, in the central Gaza Strip, killing at least 10 people and wounding several others, medics said. Later on Saturday a new Israeli airstrike on a house in western Gaza City killed at least five Palestinians and wounded others, medics said, taking Saturday's death toll to at least 20. (Reuters)
