It is not yet clear who the instigators of the attacks are. The country is in a period of transition after the departure of the last contingent of U.S. troops, which took place days ago. At the same time, there are growing signs of rupture within the government, formed last year with great difficulty.
Vice President Tariq al-Hashemi, of the Sunni party-Iraqiyya, has been accused of supporting terrorism. To protest the whole group of al-Iraqiyya is boycotting the parliament and accuse the Prime Minister al-Maliki, a Shiite, of wanting to monopolize power.
Hashemi denies the charges against him and has for now taken refuge in Erbil, in Kurdistan, under the protection of the regional government. Maliki has asked that he be brought to justice.
