Finding God in a Dog

I don't know enough about the methodology to judge it, but it's interesting:

In total, 64 cities are categorised as 'extreme risk' in Verisk Maplecroft's new Global Alerts Dashboard (GAD), an online mapping and data portal that logs and analyses every reported terrorism incident down to levels of 100m² worldwide. Based on the intensity and frequency of attacks in the 12 months following February 2014, combined with the number and severity of incidents in the previous five years, six cities in Iraq top the ranking. Over this period, the country's capital, Baghdad, suffered 380 terrorist attacks resulting in 1141 deaths and 3654 wounded, making it the world's highest risk urban centre, followed by Mosul, Al Ramadi, Ba'qubah, Kirkuk and Al Hillah.

Outside of Iraq, other capital cities rated 'extreme risk' include Kabul, Afghanistan (13th most at risk), Mogadishu, Somalia (14th), Sana'a, Yemen (19th) and Tripoli, Libya (48th). However, with investment limited in conflict and post-conflict locations, it is the risk posed by terrorism in the primary cities of strategic economies, such as Egypt, Israel, Kenya, Nigeria and Pakistan that has the potential to threaten business and supply chain continuity.

A news article:

According to the index, which ranks world cities by the likelihood of a terror attack based on historic trends, 64 cities around the world are at "extreme risk" of a terror attack.

Of these, the majority are in the Middle East (27) or Asia (19).

Some 14 are in Africa, where the rise of Boko Haram and al-Shabaab as well as political instability have increased risk.

Three are in Europe -- Luhansk (46) and Donetsk (56) in Ukraine, and Grozy (54) in Russia -- while Colombia's Cali (59) is the only South American city on the list.

No US city makes the list.
