Despite a spate of bloody incidents that made global headlines, the total number of deaths in terrorist attacks fell last year by 14 percent, a US government report said today.
While the Islamic State group remains the major threat and carried out devastating attacks in France, Lebanon and Turkey -- violence and total deaths decreased in Pakistan, Iraq and Nigeria.
According to figures compiled for the US State Department, there were an average of 981 "terrorist attacks" per month worldwide in 2015, killing a total of 28,328 over the year.
This represents 13 percent fewer attacks and 14 percent fewer deaths than in 2014, according to the National Consortium for the Study of Terrorism and Responses to Terrorism (START).
But while the global picture could be seen as encouraging, the figures record huge increases in indiscriminate political violence in Turkey, Bangladesh, Egypt, Syria and the Philippines.
The START figures were released today as an annex to the State Department's annual strategic assessment -- "Country Reports on Terrorism" -- prepared for the US Congress.
This warned that the "global terrorist threat continued to evolve rapidly in 2015, becoming increasingly decentralized and diffuse."
The report also placed some of the blame on nation states, warning that extremists exploit frustrations "where avenues for free and peaceful expression of opinion were blocked."
Where countries, including US allies, have rigged judicial systems and abuses by security forces and corrupt politicians go unchecked, violent non-state actors can win support.
But the single greatest threat remains the Islamic State group and its growing legions of affiliates and supporters in the Middle East, Africa and South Asia.
The group has begun to lose ground to US-backed forces in its self-declared "caliphate" in Syria and Iraq, and it has begun to struggle to find funds, the report concludes.
But the IS group has expanded its territory in Libya, and its branch in Egypt's Sinai peninsula has gained strength, attacking local security forces and claiming the bombing of a Russian airliner.
The group has a small toehold in Afghanistan and in 2015 ordered or inspired attacks "by individuals or small groups of self-radicalized individuals in several cities around the world.
