Eight North Koreans sought political asylum on Thursday at the Danish embassy in Hanoi, a Vietnamese diplomatic source said.

The six women and two men entered the Danish compound at about 10am (0300 GMT), the source said, adding they were accompanied by a South Korean national.

"These people came to Vietnam from China with tourist visas through the border at Lang Son province," said the source.

The Danish ambassador declined to reveal the number of people involved or to clarify whether they were seeking asylum.

"I can confirm that some persons who claim they are North Koreans are at the embassy," ambassador Peter Lysholt Hansen told AFP .

In July 2007 four North Koreans sought refuge in the Danish embassy in Vietnam hoping to get to South Korea, where they were reportedly later sent.

Similar incidents have also occurred at other embassies in Hanoi.
