I wonder if Islam (Wahhabi style) had a big role in this.
"Suicide bombers struck in Iraq for a third consecutive day on Wednesday, killing at least 15 people in two attacks in the province of Diyala and raising fears of a renewed insurgent campaign targeting Iraqi security forces and government officials.
In the deadliest incident, a suicide bomber drove an ambulance packed with explosives into a police training center in the provincial capital of Baqubah, about 35 miles northeast of Baghdad. At least 13 people were killed and 70 injured in the mid-morning attack, many of them trainees with the Facilities Protection Service, which guards state institutions and government dignitaries, according to Lt. Col. Ghalib Attiyah, police spokesman for the province of Diyala.
In the second attack, Aattiyah said, a man wearing an explosive vest detonated himself near the convoy of a top provincial official during a gathering of Shiite pilgrims in the district of Khalis, north of Baqubah. The blast killed two and injured 15, including the official, Sadiq al-Hussaini, the deputy chairman of Diyala's provincial council.
It was not immediately clear whether the bomber was targeting the official or the pilgrims, who are frequently attacked by Sunni extremists. Attacks on pilgrims are expected to escalate in the coming days as people set out to participate in commemorations for the Shiite religious holiday of Arbaeen next week."
