At least six powerful explosions were reported to have rocked Maiduguri, Borno State on Tuesday night.

The explosions occurred between 10:45 and 11:00pm.

About four explosives were said to have detonated simultaneously while two other loud sounds were also heard about 15 minutes later.

Unlike the first explosions, the latter blast had a wide-range sound effect, echoing in across the metropolis and forcing roofs to shake.

It is not clear where the blast occurred and efforts to get the details of the blasts were not successful as none of the official security spokespersons was available for comments.

A series of blasts have hit the metropolis recently, the latest happening on Monday where 12 persons were said to have died.
