Hamas has denounced the Israeli army for the massive attack on Gaza City’s Shujaiya district that killed at least 29 people and left nearly 80 others missing, Al Jazeera reports.

“The ongoing massacres against our people, with American support, are a stain on the international community’s face,” Hamas said in a statement. “The brutal crimes committed in full view of the world against innocent, defenceless civilians will not go unpunished and will not be forgotten.”

Hamas also criticised the “timid” response of Arab and Muslim nations. “It is unacceptable to leave our people alone in this fateful confrontation without real support that rises to the challenge and the crime.”

The group called on countries to pressure Israel and the US to stop bombing the Strip.
