Military authorities in central Nigeria say they have worked out strategies to track down armed assailants attacking communities in Plateau State.

This is as gunmen believed to be herdsmen are reported to have killed about 20 people in series of attacks in the State's north within the past one week.

An official statement by Major Umar Adams, the spokesperson of the  Special Task Force in the state says security measures have been reinforced with 'intense' patrols in the areas recently attacked to prevent further damages.

The statement confirms the killing of two people in Kachudu village in the State's Bassa Local Government Area, last Sunday following what appeared to be reprisal attack by herdsmen who had reported the killing of their cow by suspected locals.

Same Sunday, 11 people were killed by people believed to be herdsmen in Lopandet community in Dwei, Du, Jos South LGA with some 12 critically injured.

This was followed by the killing of another five in Gana-ropp village, in Barkin Ladi LGA also by suspected herdsmen on Tuesday.

Unconfirmed reports also say on same Tuesday, an undisclosed number of persons were shot to death by people believed to be government military personnel in Gada Biyu area, Jos North following the discovery of the corpse of a beheaded Mobile Police officer in the town's U-tan community.

While officials were still to confirm the reports, sources in Barkin Ladi LGA said on Thursday that some armed attackers invaded Nding Susut village in the locality in the morning, killing three.

All these are in addition to the killing of 15 last week in Abonong village of Foron district and Wereh village of Ropp district both in Barkin Ladi LGA as well as Butura Kampani village of Bokkos district in Bokkos LGA of the State.

No arrest has been made in connection to the attacks but state government authorities have assured of sustained efforts to rid the state of violence.
