Abductions in Nigeria

BBC article on abductions of ex-pat oil workers in Nigeria. This has been going on for a while, and is a lucrative revenue source for anti-government forces. A British oil worker was killed during a rescue attempt last week, and it's interesting to read a quote from an oil company security official that says the government should not conduct any rescue operations. Up until now, all of the abductions have been resolved with negotiations - with speculation that good-sized ransoms have eventually been paid. A potential NGO security concern is what happens if the oil companies create hard enough targets to prevent or substantially decrease employee abductions. Will the militants look elsewhere for softer targets? This could create an adverse situation for humanitarian organizations, considering the deep pocket oil companies appear to have already set a "pay for release" precedent.
