BAGHDAD (AP) — A consulting and analysis firm says attacks by the Islamic State group have jumped by more than 40 percent per day in the third quarter compared to the previous three months.

The study, released Thursday by IHS Jane's Terrorism and Insurgency Center, says that from July through the end of September 2015, the Islamic State group claimed a total of 1,086 attacks worldwide, with a 42 percent increase in the average daily number of attacks by the group.

The IHS report highlights Islamic State activity across the area that it has claimed as its territory, including Egypt, Libya, Yemen, Afghanistan, Pakistan, Nigeria, Saudi Arabia, the North Caucasus and Algeria, in addition to the group's operational heartland in Iraq and Syria.
