A Nigerian oil workers' union says it has suspended a nationwide strike aimed at forcing the government to lower the price of diesel.

Officials from Nigeria's National Union of Petroleum and Gas Workers Monday said they called off the strike after the government agreed to address their demands.

Union officials say they are giving the government two weeks to come up with a plan to lower diesel prices, which have more than doubled in recent weeks.

Long lines formed at gas stations across the country after the strike began Friday, as drivers feared the strike could disrupt supplies.

Nigeria is Africa's biggest crude exporter.  But attacks on oil pipelines and the kidnapping of foreign workers have significantly cut Nigeria's output and contributed to record high oil prices around the world.
