North Korea 'moves mid-range missile'

North Korea has shifted a missile with "considerable range" to its east coast, South Korea's foreign minister says.

Kim Kwan-jin played down concerns that the missile could target the US mainland, and said the North's intentions were not yet clear.

Pyongyang earlier renewed threats of a nuclear strike against the US, though its missiles are not believed to be capable of carrying nuclear warheads.

The US is responding to North Korea by moving missile defence shields to Guam.
