The United States has delivered 50 armored vehicles, 40 artillery pieces and 50 grenade launchers to Lebanon worth $50 million.

The equipment is part of the aid package that has crossed $220 million in the past year to counter threat from militant groups in Syria, Reuters reported.

Fighting between Islamic State and other Islamist militant groups in Syria often flares in the mountains along Lebanon’s northern frontier and the violence has periodically spilled across the border.

The Lebanese Army is preparing a separate battle against terrorist groups, Baalbek and Al-Qeeda. The Army conducted an intensive artillery shelling on the IS sites accompanied by air strikes by military helicopters on Wednesday, Aljoumhouria reported Thursday.

The US has spent more than $1.4 billion providing the Lebanese Army with weapons, equipment and training to boost its capabilities.

The US will be sending two Super Tucano light attack aircraft in October and another two in 2018 as well as the first batch of 32 M2 Bradley armored fighting vehicle.
