Bahrain is ready to commit ground troops to Syria as part of a U.S.-led coalition against the Islamic State group, the Persian Gulf island state said on Friday, a day after its larger neighbor and close ally Saudi Arabia announced a similar pledge.

Bahraini ambassador to Britain Sheikh Fawaz bin Mohammed al-Khalifa said Bahrain would commit troops to operate "in concert with the Saudis" under what he called a unified military command of Persian Gulf Arab states.

He added that the United Arab Emirates, a fellow member of the Saudi-dominated Gulf Cooperation Council (GCC), was also ready to commit troops, echoing an assertion made late last year by UAE Foreign Minister Anwar Gargash.

Saudi Arabia said on Thursday it was ready to participate in any ground operations in Syria if the U.S.-led alliance decides to start such operations, an adviser to the Saudi defense minister said.

The Bahraini ambassador said the Saudi initiative in Syria was meant to combat both the Islamic State and "the brutal Assad regime," a reference to President Bashar Assad, a bitter foe of Saudi Arabia.

Fawaz also announced the GCC had decided to base a new unified GCC naval operations center in Bahrain.

"The establishment of a joint (Gulf Arab) force shows clearly and unequivocally that under the leadership of Saudi Arabia, the Gulf states are determined to take positive action within the region and globally to combat terrorism and extremism, from whatever quarter they emanate," he said.
