Four Hong Kong passport holders Sunday were confirmed missing in the aftermath of last Sunday's huge tsunami disaster in Sri Lanka.

Cai Zhiyuan, an official with the immigration department of the Hong Kong Special Administrative Region (HKSAR) government, who is on rescue mission here, told Xinhua that nine Hong Kongers have been confirmed safe through various channels since Friday evening, making the previous figure of 6 slide down.

Cai said that the number of missing Hong Kongers was 15 on Saturday and on Sunday the number decreased to 6.

Cai, among the four-member special task force assigned by the HKSAR government, arrived in Colombo Wednesday to clinch the whereabouts of all missing Hong Kongers in Sri Lanka and the Maldives during the tsunami tragedy.

"We will do our best to offer them all the aid they need," said Cai.

The rescue team Friday brought back one holding HKSAR passport and one holding passport of China from the southern port city of Matara.

The pair, having served a local business there for years, told Xinhua that they were stuck in the battered coastal city and could not stand the poor living conditions in the aftermath of the tsunami disaster.

Cai said the team will keep on the rescue effort till the rest of missing people are found.
