Biden to meet Syrian opposition leader in Europe - White House

WASHINGTON (Reuters) - U.S. Vice President Joe Biden is set to meet with Syrian opposition leader Mouaz Alkhatib during a European trip in coming days and will discuss U.S. concerns about the Syrian conflict with Russia as well, White House officials said on Thursday.

It would be the highest-level U.S. meeting with the Syrian opposition, which is fighting to overthrow President Bashar al-Assad in a 22-month-old war that has killed more than 60,000 people and forced more than 700,000 to flee Syria, according to the United Nations.
