Before the August 14 ceasefire, Israeli military operations claimed the lives of about 1,000 Lebanese civilians, forced nearly a quarter of the country's population to flee, and demolished large parts of the country's infrastructure.
An advance party of specialists is in Lebanon to gauge the extent of the damage.
"We are ready to restore everything that we saw today within a month," Lieutenant General Ivan Tsygankov, the head of the Russian group of military specialists, said.
The group will operate in Sayda, 48 km (30 miles) south of Beirut, he said. Most of Lebanon's facilities were destroyed, Tsygankov added, but Lebanese military officials said bridges are a priority for the country, and proposed that the Russian group consider their restoration.
"It is not up to us where we will work. We will work where the Lebanese military authorities believe that bridges should be restored first," Tsygankov said.
He said that during their stay, Russians will also instruct Lebanese specialists. He added that he was satisfied with Lebanese cooperation.
