Hundreds of thousands of people in Gaza participated in the protests and general strike marking the 70th anniversary of the Palestinian Nakba, and the opening of the United States Embassy in Jerusalem.
During the first few hours of the protest on May 14th, Palestinian protesters broke into Israeli controlled territory through the barrier and set fires around Israeli military posts.
The spokesman for the Palestinian Ministry of Health Dr Ashraf Al-Qudra told 7Dnews that the number of people killed in the protest had reached 60, with almost 2,500 critically injured.
Palestinian President Mahmoud Abbas announced three days of mourning, while Egypt announced it was opening the borders with Gaza and supplying all the hospitals north of Sinai with supplies to treat injured Palestinians. Jordan sent a medical convoy.
The United Arab Emirates condemned Israel for a massacre and donated $5 million for the injured. South Africa and Ireland withdrew their Ambassadors from Israel in protest.
The UN envoy to the Middle East said on Tuesday that the killings by the Israelis were unjustifiable. Some Security Council members called for an independent investigation into the killing of peaceful protesters in Gaza.
