Twelve suspected militants have been arrested in connection with a deadly church siege in Baghdad last month, Iraq's interior minister said.
Jawad Bolani said the arrests had been made over recent days and described them as a blow to al-Qaeda.
More than 50 people were killed when militants took over the Our Lady of Salvation church on 31 October.
The gunmen seized the church during Sunday Mass, demanding the release of al-Qaeda prisoners.
It ended only when security forces stormed the church, after an hours-long stand-off.
A statement was later posted on a militant website allegedly run by the Islamic State of Iraq, a Sunni militant umbrella group to which al-Qaeda in Iraq belongs, saying it carried out the attack.
Although churches in Iraq have faced attacks in recent years, the incident was the first which involved a prolonged hostage situation.
Christians - many from from ancient denominations - have been leaving Iraq in droves since the US-led invasion in 2003, and about 600,000 remain.
