Maj. Gen. Qassim Al-Moussawi said Sunday the six suspects — who are on Baghdad’s most-wanted list — are behind the Oct. 31 siege of a church that left 68 people dead.

He said they also participated in two summertime attacks on an Iraqi army headquarters in central Baghdad. Those attacks killed a combined 73 people.

Al-Moussawi said five of the suspects are hiding in two Sunni Muslim-dominated provinces bordering Syria, while the sixth suspect has fled to that country.

Counterterror officials believe most foreign fighters cross into Iraq from Syria.
