(CNN) -- Israeli fighter jets struck a Syrian convoy suspected of moving weapons to Hezbollah in Lebanon, a senior U.S. official said Wednesday.
Fighter jets struck the vehicles because they were carrying SA-17 missile parts, a Russian-made, medium-range delivery system, and other equipment that could have been used to attack Israel, another source told CNN.
Lebanon's state-run NNA news agency dismissed the report. "The news circulated by media about an Israeli raid on the Lebanese-Syrian borders are sheer rumors," it said.
Syria, meanwhile, reported an Israeli strike targeting a research facility near the capital city of Damascus. State-run media said the attack killed two workers and injured five others.
"Israeli warplanes penetrated our airspace at dawn today and directly bombed one of the scientific research centers responsible for raising the level of resistance and self-defense in the area of Jimraya in the Damascus countryside," the military said in a statement aired on state-run TV Wednesday. "This comes after multiple failed attempts over months by terrorist groups to enter and seize the mentioned site."
It was not certain whether the U.S. and Syrian accounts of Israeli attack referred to the same or different incidents.
