The number of terrorist attacks each year has more than quadrupled in the decade since September 11, 2001, a study released on Tuesday said, with Iraq, Pakistan and Afghanistan the most affected.
The number of annual deaths in attacks, however, peaked in 2007 — the height of the Iraq conflict — and has been falling ever since. The survey reported 7,473 fatalities in 2011, 25 percent down on 2007. That figure included dead suicide bombers and other attackers.
Iraq, Pakistan, Afghanistan, India and Yemen were the five countries most affected by terrorism in descending order, it said, based on a measure giving weightings to number of attacks, fatalities and injuries and level of property damage.
