Gunmen attacked a mosque in a village in Dogo Dawa village in Nigeria's northern Kaduna state Oct. 14, killing 22 worshippers as they were leaving after prayers. Authorities called it an attack by a criminal band against followers of a vigilante group rather than sectarian violence. But that same day saw multiple attacks in the northeastern city of Maiduguri, including an armed assault on a church that killed a married couple and their child in the city Gwange area. In a separate incident, the traditional chief in Gwange, Mala Kaka, was gunned down in his home. Kaka was close to Umar Garbai el-Kanemi, a local cleric who was the intended target of a suicide blast in July. The suicide attack, attributed to Boko Haram, killed five but left Kanemi unharmed. (AFP, Oct. 15; Reuters, Oct. 14)

Four Nigerian residents and an advocacy group told a Dutch court on Oct. 11 that Shell should be held liable for damage from oil pollution in the Niger Delta. The suit, which was filed by the four villagers and Friends of the Earth Netherlands in 2008, is the first time a Dutch company has been sued for the alleged misconduct of its foreign subsidiary. Shell has maintained throughout the trial that the case should be heard in Nigeria and that the Dutch court does not have jurisdiction. Friends of the Earth Netherlands says that the case could set an international precedent encouraging victims of pollution by Western corporations to sue in the Netherlands and other nations in the EU, noting that there are hundreds of thousands of pollution victims in Nigeria alone. Shell argues that the pollution damage was caused by thieves who sabotaged the oil lines and that its local subsidiary fulfilled its duty in cleaning up the spills. A verdict in this case is expected by early 2013.

Gunmen attacked two ships off the coast of Nigeria's oil-rich southern delta Aug. 4, killing two naval troops protecting the vessels and seizing four foreign workers before fleeing.  Six naval troops were aboard the vessel, which belongs to the Sea Truck oil services company. The Nigerian navy has dispatched boats and a helicopter to the area. Sporadic attacks on oil infrastructure in the Niger Delta have continued despite a 2009 amnesty for militant groups. (AP, Radio Netherlands, Aug. 4)
