Nigerian army arrests 'Avengers' oil militants

The Nigerian army has arrested several suspected members of a militant group called the "Niger Delta Avengers", thought to be behind recent attacks on oil pipelines in the south.

The country's oil production has been severely disrupted by the attacks.
US oil giant Chevron shut down an offshore platform this month after an attack claimed by the Avengers group.

Many militants joined an amnesty programme in 2009 after an insurgency in the oil-rich delta region.
Nigeria is Africa's largest oil producer, but its economy is currently facing difficulties due to the recent drop in global oil prices.
