As dignitaries celebrated the opening of the U.S. embassy in contested Jerusalem yesterday, Israeli troops shot dead dozens of Palestinian protesters on the Gaza border. Over 50 people were killed and 2,000 wounded, this is on top of the 41 killed and more than 9,000 wounded over the past weeks.

According to Reuters Israeli troops fatally shot dozens of Palestinian demonstrators on the Gaza border on Monday as the U.S. Embassy formally moved to Jerusalem from Tel Aviv. The embassy move fulfilled a Trump campaign promise but infuriated Palestinians and drew criticism that Washington had undercut its own peace efforts.

Palestinian Health Ministry officials said 58 protesters were killed and 2,700 injured by live gunfire, tear gas or other means. Israeli Prime Minister Benjamin Netanyahu said Israel was acting in self-defense against the coastal enclave’s ruling Hamas group.

At 4:43 AM EDT, Time Magazine reported Palestinians to observe a general strike today to mourn the dozens killed by Israeli army fire in the single deadliest day in Gaza since a 2014 war. Organizers said the day would be set aside for funerals and that turnout for any new protests on the border with Israel would likely be low.

The Islamic militant Hamas, which rules the territory, had initially said mass border protests would continue Tuesday. This day marks the 70th anniversary of what Palestinians call their “nakba,” or catastrophe — the uprooting of hundreds of thousands in the Mideast war over Israel’s 1948 creation.
