The onslaught came a day after Chad sent troops across the border to flush the jihadists out of the Nigerian town of Gamboru, which lies some 500 metres (yards) from Fotokol on the other side of a bridge.
Chad's army said it had killed more than 200 Boko Haram militants in the intervention -- the first by regional forces against Boko Haram on its home ground. But some of the insurgents escaped, it added.
There were also Boko Haram bodies "everywhere," the source added.
"Boko Haram inflicted so much damage here this morning. They have killed dozens of people," Umar Babakalli, a resident of Fotokol, told AFP by telephone.
Several residents said civilians' throats were slit and that the town's main mosque was torched.
"They burnt houses and killed civilians as well as soldiers," a source close to security forces said.
After several hours of clashes Cameroonian troops, backed by Chadian forces who scrambled back from Nigeria to help guard the town, managed to repel the assault.
On Tuesday, nine Chadian soldiers were killed and 21 were injured in Gamboru after around 2,000 troops backed by armoured vehicles poured across the border to take the fight to Boko Haram after days of clashes.
