BEIRUT (Reuters) - The United States delivered 50 armoured vehicles, 40 artillery pieces and 50 grenade launchers to the Lebanese army on Tuesday, part of its efforts to bolster Lebanon against a threat from militant groups in neighbouring, conflict-ridden Syria.
The equipment, worth $50 million, is part of an aid package that has now topped $220 million this year, making Lebanon the fifth-biggest recipient of American military assistance, U.S. ambassador Elizabeth Richard said during the delivery.
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.
Eight Islamic State suicide bombers targeted a Christian village in Lebanon near the Syrian frontier last month, killing five and raising fears of a new campaign of attacks.
Fighters from Islamic State and other groups also stage regular incursions across the poorly demarcated border around the northern Lebanese town of Arsal, which they briefly overran in 2014 before the army drove them out.
Lebanon has a weak government and a number of countries support its armed forces as a bulwark against destabilisation in a country where around a quarter of the population are Syrian refugees.
This year Saudi Arabia, traditionally an important financial backer of the Lebanese state, suspended $3 billion in aid to the security forces over what it saw as growing closeness between Beirut and Iran, Riyadh's main regional foe.
Syria once dominated its smaller neighbour, whose own sectarian fissures fuelled a 15-year civil war from 1975-90. Lebanon's Iran-backed Hezbollah movement has fought alongside Syrian government forces in Syria's civil war since 2013.
