North Korea’s young leader Kim Jong-un is waiting for United States President Barack Obama to make a phone call to Pyongyang to discuss easing tensions on the Korean peninsula, according to Russia’s news agency Itar-Tass.

The report cited United Kingdom diplomats, saying Pyongyang was demanding the U.S. president personally call Kim Jong-un as one of the conditions to relieve the current conflict at hand.

Itar-Tass also quoted the U.K.’s Sky News as saying North Korea currently has eight nuclear warheads.

The report said, however, the warheads are still too large to fit onto the tip of a ballistic missile or any other kind of missile.
