Here is how USA today describes it:
BAGHDAD (AP) — Militants in Iraq targeted Christians in three separate Christmas Day bombings in Baghdad, killing at least 37 people, officials said Wednesday.
In one attack, a car bomb went off near a church in the capital’s southern Dora neighborhood, killing at least 26 people and wounding 38, a police officer said.
Earlier, two bombs ripped through a nearby outdoor market simultaneously in the Christian section of Athorien, killing 11 people and wounding 21, the officer said. […]
They somewhat redeem themselves here however:
There was no immediate claim of responsibility for the attacks, but Iraq’s dwindling Christian community, which is estimated to number about 400,000 to 600,000 people, often has been targeted by al-Qaeda and other insurgents who see the Christians as heretics.
Kinda reminds me of the last Celtic v Rangers game over here, every ones is a Christian, with Christian attackers and the victims are only Christians.
