France said Wednesday it wants the UN peacekeeping mission in Lebanon to stick to its current mandate, opposing US calls to strengthen the force's authority to deal with arms movements by Hezbollah, the Shiite militia.

Anne Gueguen, France's deputy permanent representative to the United Nations, told reporters her government saw no need to change the 2006 Security Council resolution that sets the mission's current mandate, which expires at the end of August.

"We want to keep the mandate as such," she said, adding that "does mean there won't be any change in the resolution."

Guegen spoke before the start of close door UN Security Council consultations on whether to extend the mandate of the United Nations Interim Force in Lebanon for another year. 

After the talks, Russian ambassador Vassily Nebenzi said his government also saw no need to change the mandate for the force, a position he said was shared by many at the session.

"We think this mandate should be renewed in the present form," he said.

The 10,500-strong UNIFIL in Lebanon has been in southern Lebanon since 1978, when it was charged with confirming the withdrawal of Israeli forces from a demilitarized zone between the two countries.

After a 2006 war between Israel and Hezbollah in southern Lebanon, the UN force's mandate was expanded to include keeping the peace and helping the Lebanese army reassert its authority in the aftermath of the conflict.

"We are for a reaffirmation of its mandate and the optimal effectiveness of its mission," the French diplomat said.

On August 7, US ambassador to the United Nations, Nikki Haley, said UNIFIL's mandate should be enhanced to prevent the spread of illegal weapons in southern Lebanon, which she blamed on Hezbollah and said threatened the region's stability.

"UNIFIL must increase its capacity and commitment to investigating and reporting these violations," she said.

France, which contributes 800 troops to UNIFIL, plans to submit a resolution extending the force's mandate for another year, Gueguen said.

"UNIFIL plays a decisive role to stabilize the south of Lebanon in a very difficult original context and it has demonstrated a stabilizing effect in the volatile, complex and troubled environment," she said. 

In a letter to the Security Council on August 4, UN Secretary-General Antonio Guterres said he wanted to look at ways to improve UNIFIL's efforts "regarding the illegal presence of armed personnel, weapons or infrastructure inside its area of operations."

A Security Council vote on renewing UNIFIL's mandate is expected on August 30.
