A militant group, Ansaru has claimed responsibility for the attack on the convoy of, emir of Potiskum in Yobe state.
The attack on the emir occurred along the Kaduna-Zaria highway on Wednesday and at least six lives were lost.
The emir was on his way to Zaria, Kaduna, on a tour of some traditional institutions in the north as part of preparations for the official inauguration of the Potiskum Central Mosque, Yobe slated for Saturday.
Analyst and human rights lawyer, Bulama Bukarti, who shared the development on Twitter, raised concerns that the attack might be a signal of the comeback of Ansaru, which was established in 2012.
One of the group’s last known attacks was in February 2013 when seven foreign nationals were kidnapped from a compound owned by the Lebanese construction company Setraco in Kano.
