GOMA, May 11 (Xinhua) -- Two western tourists were kidnapped Friday in Virunga National Park, in an ambush in the North Kivu province, in the east of the Democratic Republic of Congo (DRC).

According to officials at the Congolese Institute for Nature Conservation (ICC), which is in charge of managing the park, the two tourists were kidnapped while returning to the city of Goma accompanied by park wardens.

The two foreigners came from the Kibumba tourist site when their vehicle was ambushed. One of the park wardens who accompanied the tourists was killed in this ambush, according to Joel Wengamulay, the Communication Director of ICC.

The ICC also said that the identity of the attackers are not yet known. But more details about this incident will be given.

Since the beginning of the year, armed attacks have been increasing in the eastern part of the DRC. Several armed groups active in different places brought about kidnaps and attacks.
