An organization that tracks jihadi websites says the Islamic State group has published an infographic saying its West Africa division has launched more than 100 attacks in the past two months, the Associated Press reports.

SITE Intelligence Group reports Boko Haram, which joined the Islamic State group in March, has killed and injured more than 1,000 people between October 14 and December 12.

Based in Nigeria, Boko Haram has expanded its attacks into Cameroon, Niger and Chad, countries contributing to a regional force to wipe out the extremists.

The IS graphic says its West African branch has staged 67 suicide attacks and fired more than 120 rockets.

SITE says the data for the infographic posted Saturday on Twitter and Telegram was apparently collected from media reports.
