Israel regards all of the city, including the eastern sector it annexed after the 1967 conflict, as its capital. The Trump administration has said the city’s final borders should be decided by the parties.
On the day the United States opened its new embassy — the 70th anniversary of the formation of Israel — Israeli troops killed 60 Palestinian demonstrators near the border in Gaza.
It was the bloodiest day in Gaza since demonstrations began nearly two months ago in protest of Israel’s economic blockade of the territory. A mass attempt by Palestinians to cross the border fence separating Israel from Gaza was met with rifle fire from Israeli soldiers.
Protests against the embassy move were also held that day on the West Bank.
The Casablanca demonstration on Sunday was called by a coalition of four parties including the Islamist opposition group Al Adl Wal Ihsane, or Justice and Charity, which is considered Morocco’s most powerful opposition group in terms of rallying supporters on the street.
Mr. Trump formally recognized Jerusalem as Israel’s capital in December, though administration officials said this month that the American ambassador to Israel would not yet work permanently out of his new office there. Instead the ambassador, David M. Friedman, will split his time between Jerusalem and Tel Aviv, allowing him to continue to host officials whose countries oppose the American embassy move.
