North Korea fires two cruise missiles: Source

Early on Wednesday, North Korea fired two cruise missiles from the west coast town of Onchon, a South Korean military source said.

It added that the South Korean and the United States military authorities were analysing details of the missiles' flight, including the range.

The launches come as South Korea and the United States kicked off their four-day preliminary joint drill on Tuesday, in preparation for the long-suspended live field training Ulchi Freedom Shield, which is to take place from August 22 to September 1.

The two allies have scaled back combined military drills in recent years, because of Covid-19, as well as to lower tensions with the North, which has accused the exercises of being a rehearsal for future attacks.

Meanwhile, on Tuesday, the Pentagon on Tuesday said that the US, South Korea and Japan participated in a ballistic missile defence exercise off Hawaii's coast last week — the first such drills since 2017, as relations between Seoul and Tokyo hit their lowest in years.

Pyongyang had battled against a Covid-19 outbreak for months before declaring victory over the virus last week. The North, however, has been observed preparing for a possible nuclear test, which would be its first since 2017.
