Palestinians on their way to receive aid from a distribution site in southern Gaza have come under fire for a third consecutive day, with nearly 30 people killed and dozens wounded, according to the Palestinian Ministry of Health and Nasser hospital.

Palestinian health officials and witnesses say Israeli forces fired on people as they headed toward an aid distribution site Tuesday, killing at least 27, in the third such incident in three days.

The Israeli military said its troops fired on people who strayed from a designated route toward a food distribution site. It was the latest deadly incident involving a contentious new aid system.
