At least 55 Palestinians were shot and killed by Israeli fire yesterday during protests along the Gazan border against the opening of a US embassy in Jerusalem, according to Palestine’s WAFA news agency. As many as 2,771 more Palestinians were injured, with around half of these injuries caused by live ammunition from Israeli forces. The Associated Press describes it as the “deadliest day there since a devastating 2014 cross-border war.”

Egypt sent humanitarian aid, including food and medical supplies, into the Palestinian enclave and kept the Rafah border crossing open yesterday, Al Masry Al Youm reports. The Egyptian Foreign Ministry also put out a statement yesterday condemning the “serious escalation.” Egyptian officials on Sunday had urged Hamas officials, who were in Cairo for talks, to de-escalate the tension, but US President Donald Trump’s decision earlier this year to move the US embassy to Jerusalem was met with backlash from the get go. A number of organizations yesterday also condemned the move, including Egypt’s Al Azhar, the Organization of Islamic Cooperation, as well as Russian and Turkish diplomats and officials. The Arab League also called the move “illegal” and said it would hold an ”urgent” meeting on Wednesday to discuss their official response.
