Foreign fighters in Syria

Let me get this straight as I try hard to understand the standards of Western media: so the influx of foreign fighters into Syria (including from Lebanon) is not as worrisome as the rumors of Hizbullah fighters in Syria.  Furthermore, there has been actual sighting and capture of foreign fighters on the side of the Free Syrian Army gangs but has there been one sighting or capture of one Hizbullah fighter in Syria--the kidnapping of elderly and sick Lebanese Shi`ite pilgrims by the heroes of the Free Syrian Army gangs notwithstanding.
