Baghdad has been placed on top in the list of most dangerous city worldwide while Belfast in Europe has been named as most dangerous city in Europe.
According to reports, Baghdad saw 380 attacks that left 1141 people dead and over 3,600 people injured.
1,300 commercial hubs and urban centres have been included in the analysis by global risk analytics company Verisk Maplecroft.
London has been placed at 400 rank as the city did not witness a terror incident since the 7/7 bombings. Paris, however, has listed into the top 100 cities following the Charlie Hebdo shooting in Januray.
The company has taken every reported terror incident around the world in the 12 months up to March 2015, and combined that with the longer-term record of attacks in the previous five years, to come up with its rankings.
The analysis has found 12 capital cities around the world as facing an "extreme risk" of terror attacks, including Nairobi in Kenya and Lagos in Nigeria.
The report said Paris had witnessed one of the steepest rises year-on-year due to the severity of the terrorist attack in January 2015 that left 17 people dead.
Baghdad , Mosul, Ramadi, Baquba, Al Hillah, Karbala and Kirkuk in Iraq, Kabul, Kandhar and Jalalbad in Afghanistan, Quetta, Peshawar, Hassu Khel and Karachi in Pakistan and Mogadishu in Somalia and Benghazi in Libya has been ranked as top 16 dangerous city in the world.
Jos, Abuja and Kano in Nigeria; Saana in Yemen; Lahore, Rawalpindi in Pakistan and other cities from across the world have been put in the list.
