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 Tuesday.
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.
