The United Arab Emirates and Bahrain have both officially signed US-brokered deals to normalise ties with Israel.
It has been described as a betrayal by the Palestinians.
But US President Donald Trump says it represents the dawn of a "new Middle East" and predicted more countries would follow the move.

Historic event of the signing Diplomatic Agreement between State of Israel, United Arab Emirates and Bahrain.
Bahrain follows United Arab Emirates to normalise ties with the State of Israel. Very soon Saudi will be joining the Arab Nations who want to normalise relationship with Israel.
The first commercial flight from Israel to the UAE has landed, marking a major step in normalising relations after the announcement of a peace deal.
The El Al airliner made the three-hour trip, carrying a delegation of Israeli and US officials.
The flight was allowed to cross Saudi Arabian airspace, normally blocked to Israeli air traffic.
The UAE became only the third Arab country in the Middle East to recognise Israel since its founding in 1948.
On Saturday the UAE repealed a law boycotting Israel which had been in place since 1972, and earlier this month the two countries opened direct telephone services for the first time.
