The US military’s top commander in the Pacific has said an advanced missile defence system in South Korea aims to bring North Korean leader Kim Jong-un “to his senses, not to his knees”.
Adm Harry Harris, head of US Pacific Command, told Congress the US would be ready “with the best technology” to defeat any North Korean missile threat.
The US has also deployed warships and a submarine to the Korean peninsula.
China argues that the US Thaad missile system will destabilise security.
Three people were taken to hospital after protesters clashed with police as the anti-missile system was being delivered to a former golf course in South Korea on Wednesday.
