Nigeria occupies nineteenth position on the list of "extreme risk" countries and territories, according to the latest Terrorism Risk Index (TRI) released by Maplecroft.
Maplecroft, a United Kingdom-based risk analysis and mapping firm, has an international team of 75 multidisciplinary experts-including over 50 research analysts.
It provides services used extensively by leading global corporations across all sectors, governments, United Nations agencies and international non-governmental organisations.
It developed TRI to enable business to identify and monitor the risks posed by terrorism to employees and assets in 197 countries.
In the latest TRI released by the firm, 20 countries and territories were rated as "extreme risk," with Somalia, Pakistan, Iran and Afghanistan topping the list in that order. These top four countries also sustain over 75 per cent of world's fatalities from terrorism.
Other countries rated as extreme risk include the newly independent South Sudan (5), Yemen (6), Palestinian Occupied Territories (7), DR Congo (8), Central African Republic (9), Colombia (10), Algeria (11), Thailand (12), Philippines (13), Russia (14), Sudan (15), Iran (16), Burundi (17), India (18), Nigeria (19) and Israel (20).
Other categories of ranking include high risk, medium risk, low risk, and no data countries.
The UK-based risk advisory company stated on it's website that none of the major Western economies fall within the 'high' or 'extreme risk' bracket.
It rated as "medium risk", UK which was ranked 38 because of the deteriorating security conditions in Northern Ireland, while United States was ranked 61 and rated as "low risk."
The latest TRI also noted that there is a 15 per cent increase in terrorist attacks globally.
The risk advisory firm said the latest index was based on data available to calculate the frequency and lethality of terrorist incidents over the 12 month period prior to April 1, this year.
It also includes a historical component assessing the number of attacks over five years and the risks relating to countries' geographic proximity to terrorist hotspots.
On Nigeria, it said, "Security conditions in Nigeria remain fragile and a source of concern for investors."
It cited the activities of the Movement for the Emancipation of the Niger Delta (MEND), which it said had launched attacks beyond the Delta, in Abuja, the nation's capital city.
It is, however, important to note that the ranking of Nigeria was based on the data available on terrorist incidents over the 12 month period prior to April 1, this year.
Lately, there had been series of bomb attacks in the northeastern states of Borno and Bauchi, and North-central state of Niger by Boko Haram. Mid-June, the group struck in the heart of the nation's capital detonating a bomb at the car park of the Nigeria Police headquarters.
