The convoy of Borno State Governor Babagana Zulum again came under attack earlier on Sunday on his way out of Baga, Channels Television has reported.
According to the report, Zulum departed Baga at about 10:30 after a two-day visit to receive indigenes of the town back home after 21 months of exile.
Few kilometres away from Baga, unknown assailants believed to be Boko Haram opened fire on the escort of the governor.
The convoy was being escorted out of Baga by the military who replied the gunshots and cleared the way for the governor.
The attack is coming barely 48 hours after officials of Borno State were ambushed on the same route while travelling to Baga to join the governor who had flown in via an Air Force chopper.
30 persons including 14 security officials died in the earlier attack.
Zulum was a subject of a similar attack on that Boko Haram-infested route in July, where he was lucky to escape assassination at the hands of the murderous group.
About 3 million people have been displaced in more than a decade of terror activities by Boko Haram. Scores of civilians are still trapped in remote communities unable to flee because of insecurity on the roads.
The violence, which has killed more than 30,000 people, has spread to neighboring Niger, Chad and Cameroon, prompting a military response.
Borno state is the epicenter of the insurgency.
