As efforts towards a ceasefire increase, Sebastien Lecornu told AFP that he had raised the prospect of "operational support" for the Lebanese armed forces during his trip.

"I have reiterated to each counterpart that we need them to support the Lebanese armed forces," he said after visits to Qatar and Saudi Arabia.

"Both in the central role they play in welfare matters, and in the security aspect. We will have to think about more operational support on the military side."

Lecornu was speaking in the UAE capital Abu Dhabi before meeting President Sheikh Mohamed bin Zayed at the end of his three-country tour.

Diplomatic efforts are intensifying to secure a ceasefire based on United Nations Security Council Resolution 1701, which ended the 2006 war between Hezbollah and Israel.

The resolution called for the deployment of Lebanese government forces and United Nations peacekeeping force UNIFIL in areas south of Lebanon's Litani River near the Israeli border, as well as the withdrawal of Israeli forces.

"There isn't a better solution at this stage than to respect Resolution 1701 and to support the Lebanese armed forces," Lecornu said.

But "to secure the border between Israel and Lebanon, and to reinforce Lebanon's sovereignty, the armed forces must be properly armed", he added.

The Lebanese army is envisioned as having a greater role in maintaining stability along the border in the event of a ceasefire, though it currently struggles to meet the basic needs of its 80,000 soldiers.

It has previously received financial assistance from Qatar and the United States to pay salaries.

Last month, a conference in Paris raised $200 million to support the Lebanese armed forces, on top of $800 million in humanitarian aid for the country.

Israel expanded the focus of its operations from Gaza to Lebanon in late September, vowing to secure its northern border to allow tens of thousands of people displaced by cross-border fire to return home.

Since the clashes began with Hezbollah attacks on Israel, more than 3,510 people in Lebanon have been killed, according to authorities there, with most fatalities recorded since late September.

The Lebanese government says it is ready to deploy the army to the border to safeguard a ceasefire, and plans to recruit 1,500 more soldiers.

Prime Minister Najib Mikati said last month that 4,500 military personnel were in the south and that he wanted to raise their number to 7,000-11,000.

Lecornu's tour also comes two weeks before French President Emmanuel Macron arrives in Saudi Arabia for a visit focused on defence and investment in new technologies.
