VIDEO: Iran and UK FMs comment on nuclear issue

Iran's foreign minister and European Union counterparts held talks on Monday in an effort to reach a deal over Tehran's nuclear program before a June 30 deadline.

Mohammad Javad Zarif held private talks with counterparts from Germany and France, before meeting with a group of EU leaders on the sidelines of a meeting of top EU diplomats in Luxembourg.

Zarif predicted intense and difficult days ahead before the deadline to strike a deal with world powers over Tehran's nuclear programme.

British Foreign Secretary Philip Hammond, who also met with Zarif, said diplomats are "going to pull all the stops out" to reach an agreement by the deadline.
