An Israeli airstrike against a police vehicle on Sunday killed three people in the Nuseirat camp in the central Gaza Strip, according to health authorities, hours after another person was killed in an attack in northern Gaza.
Doctors and police sources said the three men killed in Nuseirat were members of the Hamas-led police force.
Ten people were also injured in the attack, according to doctors.
Earlier on Sunday, a separate airstrike killed one person — identified as the leader of one of the armed groups affiliated with Fatah — and wounded an unknown number of other people in the Sheikh Radwan neighborhood in northern Gaza.
