In remarks delivered after landing, the secretary invited "moderate voices" within the Taliban to renounce violence. He also called on Pakistan to stop providing safe haven to terrorists.

The State Department said the withdrawal from the United Nations' cultural agency will take effect Dec. 31, 2018. The U.S. had cut funding to the group years ago for offering Palestinians membership.

The secretary of state denied a report that he considered stepping down, but did not deny that he called the president a "moron" after a hotly political speech before the Boy Scouts over the summer.

The tweets from the president come just one day after Secretary of State Rex Tillerson noted the U.S. has channels of negotiation "open to Pyongyang."

The move follows reports in August that U.S. diplomats in Havana had been subjected to mysterious "sonic" attacks that led to hearing loss, headaches and other health problems.

When asked if Americans should be worried about tensions with North Korea, Secretary of State Rex Tillerson replied, "I think Americans should sleep well at night."

North Korea is blaming the United States and threatening "something thousands of times worse" in response to a package of sanctions that the U.N. Security Council passed unanimously over the weekend.

Americans currently in North Korea were told to depart by the end of August. Journalists and aid workers may apply for exemptions from the ban.

The U.S. secretary of state will also visit Qatar and Saudi Arabia. The latter has joined three other countries in isolating tiny Qatar. The shuttle diplomacy marks a shift in approach for Tillerson.

The truce, for a section of the country's southwest, also includes Jordan and Israel. Several such cease-fires in the past have been short-lived.
