In the message on Monday, Larijani condemned the terrorist attacks in Afghanistan, and described terrorist groups as a major threat to the security, tranquility and progress of the region.
"I am sure that these blind terrorist acts will not undermine the will and determination of the great nation of Afghanistan to confront those elements who threaten the country's tranquility and progress," the message said.
Larijani further voiced Iran's readiness for joint cooperation with Afghanistan to strengthen and consolidate durable security and stability in the region.
