A boat carrying up to 150 Rohingya Muslims fleeing a cyclone has capsized off Myanmar's coast, the U.N. said Tuesday, heightening fears over the storm which threatens camps for tens of thousands of displaced people.

A tunnel at a mine in the remote east of Indonesia caved in Tuesday with around 30 workers inside, the U.S. operator and police said.

Tehran on Tuesday played down a decision by the United States to boycott meetings of the U.N. Conference on Disarmament when Iran takes over the body later this month.

South Korean President Park Geun-Hye said Tuesday she wants talks with North Korea on removing raw materials and finished products from a joint industrial complex closed by military tensions.

A U.S. Marine officer will be court martialed for his alleged role in the scandal sparked by a video that showed soldiers urinating on the dead bodies of three Afghans, the Marine Corps said Monday.

Seeking to quell a growing scandal, President Barack Obama said Monday it would be "outrageous" if U.S. tax authorities targeted conservative groups fiercely opposed to his White House.

Ariel Castro, the man accused of holding three young women captive for a decade, had a history of violence and threatening behavior, U.S. police reports released Monday showed.
