Bahrain said late Thursday it agreed to allow UAE flights to and from Israel to overfly the kingdom, a day after a similar decision was announced by Saudi Arabia.
"Bahrain will allow all flights coming to and departing from the United Arab Emirates to all countries to cross its airspace," reported the official Bahrain News Agency, citing an official source at the Ministry of Transportation and Telecommunications.
The announcements come after the UAE and Israel agreed to normalise ties in a US-brokered agreement announced by US President Donald Trump last month.
Bahrain, like Saudi Arabia, has no official diplomatic relations with Israel.
However, both countries' decisions to open their airspace mark another concrete sign of cooperation with Israel, even after they refused publicly to follow the UAE in establishing diplomatic relations with the Jewish state.
Saudi Arabia has said it will not establish diplomatic ties with Israel until Israel has signed an internationally recognised peace accord with the Palestinians.
White House advisor Jared Kushner visited Bahrain on Tuesday, a week after a visit by Secretary of State Mike Pompeo, as the US tries to seize on the momentum of the UAE's move.
He met with King Hamad bin Isa Al-Khalifa, who said stability in the region relied on Saudi Arabia, according to state media.
