Horror moment 'ISIS' suicide bombers break into Christian church where they opened fire on worshippers

Horrifying CCTV shows two suicide bombers forcing their way past police during an attack on a Christian church in Pakistan.



At least nine people were killed and 45 injured after two ISIS fighters managed to get inside.



Several children caught up in the carnage were forced to cower behind their parents during the horror ordeal.



Militants stormed the Methodist church, which was packed with worshippers at the time, in the city of Quetta, some 65km (40 miles) from the Afghan border.



CCTV shows one of the attackers walking past the church and suddenly pull a machine gun out from under his top before he races towards the entrance.



He fights with a guard before e and an accomplice manage to force their way inside after he leaps over the gate.



Police guards then charged at the men as they opened fire while heading towards the church where 400 worshippers were gathered.



One of the men then detonated his bomb vest and the other was stopped in a gunfight with police.



Two more attackers fled and a search operation is under way following the attack yesterday, according to reports.



Sarfraz Bugti, the Balochistan region's home minister, said if the men got any further, there could have been hundreds of casualties.



Islamic State has claimed responsibility for the attack.



Harrowing footage from inside the church shows a lone Christmas tree standing amid pools of blood, smashed pews and shattered windows at the Bethel Memorial Methodist Church in Quetta City.



The video shows scenes of devastation as the blast tore through the interior of the building, splintering furniture and smashing much of front of the church.



The transept lies in ruins as shredded curtains hang near the alter.



Instruments used in the service are scattered across the floor and overturned pews lie strewn through the nave.



Provincial police chief Moazzam Jah said: "There were nearly 400 people inside the church, but the attackers couldn't get inside the services.



"We killed one of them, and the other one exploded himself after police wounded him."



Jah said the church had guards because Christian places of worship are often targeted by Islamist extremist groups.



Baluchistan has long been the scene of an insurgency by separatists fighting against the state to demand more of a share of the region's gas and minerals.



They also accuse the central government of discrimination.



The Taliban, Sunni Islamist militants and sectarian groups inked to al Qaeda and the so-called Islamic State group also operate in the strategically important region, which borders Iran and Afghanistan.



The violence has fuelled concern about security for projects in the $57 billion China Pakistan Economic Corridor, a transport and energy link planned to run from western China to Pakistan's southern deep-water port of Gwadar.



Pakistan has launched several military offensives over the last decade against the Islamist militants who want to install their own harsh brand of religion.



Although beaten and dispersed, the militants have shown resilience to launch spectacular attacks.



Early this month, three Taliban suicide bombers attacked an agriculture college in northwestern Peshawar city, killing eight students and a guard.
