CCTV footage has captured two armed militants on camera as they attempted to break into a Christian church in Quetta in south west Pakistan.
At least nine people were killed and up to 56 others were wounded in a joint suicide bomb and gun attack on Sunday.
Police guards stationed at the church entrance killed one bomber but a second managed to detonate his explosives-filled vest. Two other attackers fled the scene according to reports.
The church at the time had been packed with around 400 worshippers. Had the men got any further the death toll could have been far higher.
The self-styled Islamic State group has claimed the attack via its Amaq news agency in an online statement.
Later a vigil for the dead turned into a protest. Christian places of worship in the region which borders Iran and Afghanistan are often targeted by Islamist extremists over the Christmas season.
