Gunmen kidnapped two Canadian tourists, a Norwegian employee and a Filipina from a luxury resort island in the conflict-wracked southern Philippines, while other foreigners narrowly escaped, police said Tuesday, according to AFP.

The abductions add to a string of kidnappings of foreigners in the south since the early 1990s, most often by Islamic militants seeking to extort ransoms, although the latest culprits were not immediately identified.

Police said armed men sailed two motorboats into a marina on Samal island just before midnight on Monday and seized the four from aboard yachts, apparently knowing exactly who they wanted to abduct, police said.
