S Korea's President Yoon vows to 'fight to the end'

Embattled South Korean President Yoon Suk Yeol has defended his shock decision to declare martial law last week, saying he did it to protect the country's democracy.

In a surprise televised address on Thursday, he said the attempt was a legal decision to "prevent the collapse" of democracy and counter the opposition's "parliamentary dictatorship".

And despite growing calls for him to resign or be impeached, Yoon has suggested that he would not step down.
