Hezbollah has claimed responsibility for a missile attack that injured 4 members of the Israeli Defense Forces early Wednesday. 

From Reuters:  

In an apparent revenge attack for an Israeli air strike in Syria that killed senior Hezbollah members, the group said its "Quneitra Martyrs Brigade" had carried out Wednesday's hit on an Israeli convoy in the Shebaa Farms frontier area, prompting concerns of further escalation.

Lebanon's National News Agency said an Israeli soldier had been captured in the operation, but the Israeli military immediately denied that.

Israeli artillery fired at least 22 shells into open farmland in southern Lebanon after the strike, a Lebanese security source said, and thick smoke rose over the area.

The terror network released the following statement:  

"At 11:25 [Wednesday morning] the Quneitra Martyrs unit targeted with appropriate missile weapons an Israeli military convoy comprising several vehicles and [transporting] Zionist officers and soldiers causing the destruction of several vehicles and inflicting many casualties on the enemy."
