KANO: Yanaye Grema hid for three days between a wall and his neighbors’ house, as Boko Haram fighters ransacked his hometown of Baga on the shore of Lake Chad in Nigeria’s far northeast.

The 38-year-old fisherman already knew the attack was serious: He joined civilian vigilantes to defend the town but their simple weapons were no match for the militants’ superior firepower.

“People fled into the bush while some shut themselves indoors,” he said of last Saturday’s attack.

“The gunmen pursued fleeing residents into the bush, shooting them dead,” he told AFP from the Borno state capital, Maiduguri.

But it was only after breaking cover on Tuesday night that he realized the true scale of the attack, which it is feared may be one of the worst in the six-year insurgency.

“For five kilometers, I kept stepping on dead bodies until I reached Malam Karanti village, which was also deserted and burned,” he said.

Hiding from view between the wall and the house, behind a roadside stall and the cover of a thick neem tree, Grema said the rampaging militants unleashed mayhem. “All I could hear were ceaseless gunshots, explosions and screams from people ...,” he added.

“I remained in my hiding place until Tuesday evening.

“Every night when it was dark, I would furtively scale the fence into my house to quickly eat garri (processed cassava granules) and drink water and go back to my hide-out.”

His family was not at home. They were in Kukawa, 40 kilometers away, paying their respects after Boko Haram killed his wife’s cousin about two months ago.

“Some of the Boko Haram gunmen camped outside the Baga main market just 700 meters from my hideout,” he explained.

“At night I could see lights from the power generator they ran. I could also hear their cheering and laughter.

“Luckily on Monday some of the gunmen withdrew while others stayed in the town. This reduced their number, which made it difficult for them to patrol the whole town. It worked to my advantage.

“On Tuesday they began looting the market and every home in the town... Around 6:00 p.m. they set fire to the market and began burning homes. I decided it was time I leave before they turn in my direction.

“Around 7:30 p.m. I ventured out of my hiding and started to walk away from the noise coming from the gunmen. It was dark, so no-one could see me.”

In the bush, Grema chanced upon an old man at a nomadic Fulani herdsmen’s settlement, who advised him to move west to avoid running into the militants.

“His warning frightened me but made me more determined to get away. I thanked him and moved on,” he said. “I quickened my pace. I soon caught up with... four women. One of them was carrying a baby on her back.

“They told me they were among hundreds of women that were arrested by Boko Haram and detained in the home of the district head which Boko Haram had converted into a women’s detention center.”

Three of the women had been separated from their children, he added. Grema said he pushed out on his own, as the women were “too slow,” running and walking throughout the night, before arriving at Kekeno village near Monguno, 65km away, the following morning.

On Thursday, he took a bus from Monguno to Maiduguri.

“I will never forget this experience and I will forever be grateful to the old Fulani nomad for his life-saving advice,” he added.
