According to this Arab press article, that's what's happening.

Killings have been ongoing for a while now between Lebanese Shiite clans and the Sunni inhabitants of the town of Arsal.

Moreover, it has become obvious that the higher frequency of these events has coincided on the one hand with Hezbollah’s deepening involvement in the Syrian war and on the other with the consolidation of the relationship between Lebanese Salafist forces and their Syrian counterparts.
