TEHRAN, Feb. 9 (Xinhua) -- Russia and Iran will sign an agreement on visa-free travels of the nationals by group tours, Russian ambassador to Iran Levan Dzhagaryan said on Wednesday.

The agreement will be signed during the visit of Iranian President Hassan Rouhani to Moscow in March, Dzhagaryan was quoted as saying by semi-official Fars news agency.

The citizens of both countries will take advantage of visa-free trips in group travels organized by tours containing 5-25 passengers, he said.

"We believe this agreement is particularly important because it will significantly increase the flow of tourists both from Iran to Russia, and vice versa," he added.
