The US lodged a complaint against Syria for providing ballistic missiles to Hizbullah, shortly after Syrian President Bashar Assad denied doing so, according to documents released by Wikileaks on Tuesday.
"We are concerned about Syria's provision of increasingly sophisticated weapons to Hizbullah," US Secretary of State Hilary Clinton wrote in a February 2010 diplomatic cable classified as "secret."
"In our meetings last week it was stated that Syria is not transferring any 'new' missiles to Lebanese Hizbullah," Clinton wrote. "We are aware, however, of current Syrian efforts to supply Hizbullah with ballistic missiles. I must stress that...we strongly caution [Syria] against such a serious escalation."
