Iran's special envoy for Afghanistan expressed concern about an increase in insecurity in Afghanistan, Tasnim news agency reported on Sunday.
Mohammad Ebrahim Taherian made the remarks on Saturday and also offered Tehran's assistance in launching intra-Afghan negotiations.
"Restoration of peace and stability is not only a public demand from the people, government, and various currents in Afghanistan, but also a necessity in the course of promotion of regional cooperation and achievement of collective security," said Taherian.
On Saturday, at least 18 security agents were killed and six people were wounded in four attacks across Afghanistan, including one explosion in the capital Kabul, where a civilian was injured.
Taherian pointed to the Aug. 9 agreement at Afghanistan's Loya Jirga, or the Grand Assembly, to release Taliban prisoners, and stressed the need to prepare intra-Afghan negotiations.
Iran, Taherian added, is ready to cooperate with its neighbour country to launch such negotiations.
