Tehran interim Friday prayer leader criticized the US-led interventions by NATO for complicating the situation in Ukraine and counted call to dialogue and restraint as Iran’s policy towards the recent crisis in the European country.

Speaking in sermons of Friday prayers at Imam Khomeini Mosalla about Tehran's policies toward Ukraine crisis in recent days, Ayatollah Ahmad Khatami said that Iran's macro policy is always inviting all countries involved to be restraint and choose dialogue to resolve issues.

He went on to say, "Regardless of their religion, We are concerned bout the killing of innocent people."

US-centered interventions and provocative actions of NATO will complicate the situation in the region, he also stressed.

Elsewhere in his remarks, Ayatollah Khatami said, "Leader of Islamic Revolution allowed Iranian negotiation team to enter the talks only aimed at the removal of sanctions."

The removal of all sanctions including banking sanctions is very important, he said, adding that if the sanctions are not removed, it seems that no negotiations have been held.
