A South African court has found a Nigerian man guilty on terrorism charges for masterminding bombings that killed 12 people in 2010.
The court ruled Monday that Henry Okah was guilty on 13 charges related to the twin car bombings in the Nigerian capital, Abuja, that came as the country celebrated its Independence Day. The court has not said what sentence it will give Okah.
Authorities arrested Okah in South Africa a day after the bombings. He denied having a role in the attack.
He is accused of leading the militant Movement for the Emancipation of the Niger Delta (MEND), which he also denies.
MEND has carried out numerous attacks against Nigeria's oil industry, demanding a bigger share of the oil wealth in the Niger Delta region. Many of its members surrendered their weapons in 2009 under a government amnesty program.
