According to the sources attacker aim was the Shabak Shia in Mosul, 390 km (240 miles) north of Baghdad.
In recent months Shia Muslim pilgrims and religious sites face more attack by Anti-Shia terrorist. It is unfortunate that the government has yet to be able to stop or even preventing violence from happening.
This leaves the Shia population in Iraq to face attacks on a daily bases and fear living in their own country. Shia should step up peacefully and take control of their own security.
