At least 210 Palestinians were killed and 400 others were injured in the central Gaza Strip on Sunday after Israeli forces carried out a “rescue operation” to retrieve four captives. Reports of U.S. involvement in the operation have sparked backlash.

Al Jazeera quoted Dr Tanya Haj-Hassan with Doctors Without Borders as saying the emergency department at Al-Aqsa Hospital “is a complete bloodbath … It looks like a slaughterhouse.”

“The images and videos that I’ve received show patients lying everywhere in pools of blood … their limbs have been blown off,” she told Al Jazeera, adding “That is what a massacre looks like.”

It is reported that there are 120 captives still held in the Gaza Strip, including 43 who have been killed since October, many reportedly by Israel’s own forces.

Reported U.S. involvement in the attacks on central Gaza on Saturday, and the alleged use of the pier in the operation, has sparked intense criticism and outrage online.
