Pakistan attack video shows dramatic moment cloaked ISIS gunman opens fire with a Kalashnikov in deadly suicide bombing on Catholic church

THIS is the moment a terrorist yanks up his cloak and reveals his Kalashnikov before unleashing a deadly gun and suicide bomb massacre at a Catholic church in Pakistan.   

At least nine people are dead and 56 wounded in the horrific attack claimed by ISIS on a Sunday service in Quetta city less than a week before Christmas.

CCTV footage released by the police showed the attackers, both carrying guns, approaching the church gates.

One of them is wearing a brown cape from which he produces the automatic rifle.

His accomplice can then be seen following behind and he appears to trip up before getting back on his feet.

Meanwhile, the first gunman appears to be struggling to open the gate.

But with help from the other terrorist, he manages to scramble over into the church’s compound.

The second militant is then let in.

Worshippers sitting at tables outside the church are then seen running from the scene after spotting the killers.

Police guards stationed at the church entrance and on its roof killed one of the bombers.

But the second attacker detonated his explosives-filled vest outside the prayer hall just after Sunday services began, said Sarfraz Bugti, the provincial home minister.

ISIS has claimed the attack, the group's Amaq news agency said in an online statement, without providing any evidence for its claim.

Officials have yet to confirm who is responsible.

Police guards at the church exchanged fire with the attackers before they could enter the main sanctuary, said local police chief Moazzam Jah.

He said the attackers clashed with security forces, with one assailant killed at the entrance while the other made it inside.

"There were nearly 400 people inside the church," Jah said. "We killed one of them, and the other one exploded himself after police wounded him."

Jah said the venue - Bethel Memorial Methodist Church - was on high alert as Christian places of worship were often targeted by Islamist extremists over Christmas.

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

They also accuse the central government of discrimination.

The Taliban, Sunni Islamist militants and sectarian groups linked to al Qaeda and the ISIS group also operate in the strategically important region, which borders Iran as well as Afghanistan.

Hospital officials said two women were among the dead while another five women and two children were among the wounded.

A young girl in a white dress sobbed as she recounted the attack to Geo television, saying many people around her were wounded.

Aqil Anjum, who was shot in his right arm, told The Associated Press he heard a blast in the middle of the service, followed by heavy gunfire.

"It was chaos. Bullets were hitting people inside the closed hall," he said.

Dozens of Christians gathered outside a nearby hospital to protest the lack of security.

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 Pakistans 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.

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