WASHINGTON, Jan 31 (Reuters) - There are signs that Iran is sending growing numbers of people and increasingly sophisticated weaponry to support Syrian President Bashar al-Assad, outgoing U.S. Secretary of State Hillary Clinton said on Thursday.
"It appears that they may be increasing that involvement and that is a matter of great concern to us," she told reporters as she prepares to step down on Friday. "I think the numbers (of people) have increased ... There is a lot of concern that they are increasing the quality of the weapons, because Assad is using up his weaponry. So it's numbers and it's materiel." (Reporting By Arshad Mohammed; Editing by Mohammad Zargham)
