KANO: Nigeria’s security services have hailed the arrest of the leader of the Boko Haram splinter group Ansaru, Khalid Al-Barnawi, saying it will lead to them to other senior militant commanders.

“The arrest of Barnawi is a huge success and will have a profound effect on counter-terrorism operations in Nigeria and beyond,” one security source told AFP.

“He is a known transnational terrorist and the backbone of all Al-Qaeda affiliate groups in West Africa.”

Barnawi, designated a global terrorist by the United States since 2012, was detained on April 1 with three others in the Kogi state capital, Lokoja, and found with four Thuraya satellite phones.

The phones “provided several leads” to “high-profile Boko Haram and Ansaru elements” in the capital, Abuja, Lokoja and the central city of Jos, said another source.

“This has been our biggest breakthrough against terrorism in Nigeria ever,” said a third.

“We still have other high-ranking terrorists on our radar based on the information gathered from the phones of Barnawi and his three comrades. We will rope them in at the right time,” he added.

Barnawi is certainly a major prize for Nigerian intelligence, the Department of State Services (DSS), which called him “a trained terrorist commander” who also recruited for Al-Qaeda affiliates.

He is accused of masterminding a string of kidnappings of Westerners between 2011 and 2013.

“This arrest is a major milestone in the counter-terrorism fight,” the DSS said in a statement on April 9, with an accompanying mugshot of Barnawi.

But while security analysts agree he is the most high-profile capture since the start of the insurgency in 2009, it remains unclear what effect it will have on operations on the ground.
