Thaad: US begins deploying missile defence system in South Korea

The US military says it has begun deploying a controversial missile defence system in South Korea.

The Terminal High-Altitude Area Defense system (Thaad) is designed to protect against threats from North Korea.

The move to begin installing the system comes a day after the North launched four ballistic missiles, breaking international sanctions.

But its planned deployment has angered many in North and South Korea and around the region.
