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. South Korea has said the system would be operational by the end of the year.
US President Donald Trump has vowed to thwart North Korea’s plans to build and launch an intercontinental missile capable of reaching the US, saying in January that it won’t happen.
Many South Koreans believe the defence system will become a target, endangering people who live around the military sites, and opponents have staged multiple demonstrations.
China is also furious at deployment of the system. Commander of the US South Pacific Command, Admiral Harry Harris, said the launch confirmed the prudence of the decision to deploy Thaad.
North Korea had threatened last week to fire missiles in response to the start of the Foal Eagle US-South Korean military exercises.
The United Nations Security Council is due to meet on Wednesday in an emergency meeting requested by the US and Japan to discuss the incident.
North Korean missile launches are usually followed by global sanctions rather than military action.
