Boko Haram fighters reportedly opened fire on Governor Kashim Shettima’s convoy, killing at least three persons.
The Borno state governor was on his way to a rally ahead of the presidential election, official sources said.
The identity of the gunmen was not immediately clear, but the sources said they suspected it must have been the Islamist group that carried out the attack.
They said the gunmen opened fire at the motorcade transporting the governor on Tuesday on his way from state capital Maiduguri to the market town of Gamboru for a rally.
Two security sources who spoke to Reuters said at least three people died in the attack.
A government and a separate security source said as many as 10 people were killed during the attack.
At the time of filing this report, the governor’s spokesman could not be reached for comments.
