Bonn: Syria said Tuesday at UN climate talks in Bonn that it would join the Paris Agreement, leaving the United States as the only nation to say it will remain outside the landmark treaty.

"We are going to join the Paris Agreement," the Syrian delegate said in a plenary at the 196-nation talks, according to Safa Al Jayoussi of the IndyAct NGO, who was monitoring the session.

The United States ratified the 2015 pact, but US President Donald Trump announced earlier this year he would pull out, saying the pact did not serve US interests.
