The leader of al-Qaeda-linked Islamist group Ansaru has been arrested in Nigeria.
A military spokesman said Khalid al-Barnawi was captured in Lokoja, capital of the central state of Kogi.
The US had placed a 5 million dollars bounty on his head after branding him one of three Nigerian "specially designated global terrorists" in 2012.
Ansaru is a splinter group of Nigeria's largest jihadist group, Boko Haram, known for kidnapping foreigners.
Ideologically aligned to al-Qaeda in the Islamic Maghreb, it is also accused of killing a number of Westerners.
