The UN Security Council on Monday unanimously adopted a resolution that will clear a path for international sanctions crippling Iran's economy to be lifted.

"The draft resolution has been adopted unanimously," New Zealand ambassador Gerard van Bohemen, whose country holds the current presidency of the Security Council, announced after the vote.

On condition that Iran respects the agreement to the letter, seven UN resolutions passed since 2006 to sanction Iran will be gradually terminated, according to the text.
