Syrian President Bashar Assad traveled to the United Arab Emirates on Friday, his first visit to an Arab state since the Syrian war began in 2011, underlining warming ties with a U.S.-allied country that once backed rebels who sought his ouster.

Assad met Abu Dhabi Crown Prince Sheikh Mohammed bin Zayed Al Nahyan who "stressed that Syria is a fundamental pillar of Arab security, and that the UAE is keen to strengthen cooperation with it," Emirati state news agency WAM reported.

A video posted by WAM showed Assad smiling as he stood alongside Sheikh Mohammed in front of the Syrian and Emirati flags, as well as gesticulating and smiling during talks.
