More than 80 people were killed in Pakistan on Sunday when a pair of suicide bombers blew themselves up outside a historic church.
It's the deadliest attack ever on Pakistani Christians. Now they're demanding security from the government and the arrests of those responsible for the attack.
Hundreds of demonstrators gathered in Karachi Tuesday chanting, "Stop killing Christians!" Officials say more than 80 people were killed in Sundays bombings and more than 140 were wounded.
"I fell down and my daughter, who was in my lap, died in front of me," said survivor Tony Khadim.
The attack happened as a church service was letting out. A pair of suicide bombers blew themselves up as hundreds of worshippers were coming out of the historic church in Peshawar to get a free meal.
A spokesman for a wing of the Pakistani Taliban immediately claimed responsibility.
The bombings raise new questions about the Pakistani governments push for a peace deal with the terrorist organization.
"The whole government is shocked by this because, you know, the peace process is going on and everybody is talking about the peace process between the Taliban and Pakistani government. And in the same time, this incident happened. That shows the non-seriousness of the peace process of Talibans," Javed Rauf, with Jesus Christ Television, said.
The Taliban spokesperson said the attack was in response to drone strikes by the United States.
CBN News Sr. International Correspondent Gary Lane explained why that's causing Pakistani Christians to be targeted.
"Christians are seen aligned with the West so they attack the Christians because they know they'll get attention if they do that," Lane said.
"So that's why they target them, plus they're the weakest, they're the most vulnerable," he said.
Christians make up less than three percent of Pakistan's population. Roughly 96 percent are Muslim.
