Lebanese security officials say attackers fired a rocket at an army patrol near the Syrian border, killing two soldiers and wounding three.

The violence appeared to be the latest in tensions between Lebanese troops and Syrian Islamic extremist rebels crossing the border in a spillover of Syria's civil war. The rocket hit Friday near the army patrol outside the border town of Arsal, an area of repeated clashes, the security officials said, speaking on condition of anonymity in line with regulations.

The attack came after the army detained a Lebanese and two Syrians alleged to be part of a "terrorist cell" near Arsal. On Wednesday, jihadi gunmen crossed from Syria and snatched a Lebanese solider. Gunmen snatched around 20 soldiers and police in August.
