BEIRUT — France will soon provide weapons and military equipment to the Lebanese army as part of a $3 billion grant from Saudi Arabia to help it fight extremists encroaching into Lebanon from Syria, Defense Minister Jean-Yves Le Drian said on Wednesday.

One of the few institutions not overtaken by the sectarian divisions that plague Lebanon, the army has few resources to deal with the instability on its border and has been seeking to modernize its military hardware.

“All the work is done and the president (Francois Hollande) indicated yesterday to Mr (Saad) al-Hariri that the conditions to fulfil the contract had been met,” Defense Minister Jean-Yves Le Drian told parliament.

“This is a necessity. The Lebanese army is the last barrier that exists against the security threats this country faces.”

Former Prime Minister Hariri, who has close links to the Saudi royal family, was in Paris on Tuesday to meet Hollande. He said that another Saudi grant of $1 billion for the Lebanese army had also been finalized.

Extremists attacked and briefly seized the Lebanese border town of Arsal in August and since then the army has stepped up its efforts to prevent fighters, most notably from al Qaeda’s Syrian wing Nusra Front, from crossing into Lebanon.

Beirut has officially tried to distance itself from Syria’s conflict, but Hizbullah has sent fighters to aid President Bashar al-Assad.

Lebanon, which is still rebuilding after i­ts own 15-year civil war, has also seen clashes between gunmen loyal to opposing sides of the Syrian conflict, as well as militant strikes on the army and crossborder attacks by Syrian militants.

The contract, which was initially agreed in December, has been under intense scrutiny for several months as negotiations between Paris and Riyadh over the deal have proved more complicated than first imagined.
