Officials say Islamic militants have burned 11 people to death inside their homes in northeastern Nigeria, where frequent attacks have claimed at least 130 lives in the past four days alone.

The attack late Monday on Jakana village in Borno state occurred about 6 miles (10 kilometers) from a village where 39 people were slaughtered on Saturday, said Nigerian Senator Ahmed Zannah.

Violence has escalated in recent weeks in three northeastern Nigerian states that have been under emergency rule for over nine months.

Officials and residents blame the attacks on Boko Haram, an Islamic insurgent group that has killed thousands of people in the past four and a half years.

Zannah said Tuesday that residents in Jakana had been warned of an attack, and many there and in neighboring villages had fled into the bush before the gunfire began. The victims, he says, were all too old to flee.
