Ash-har Quraishi: Gruesome scene at Pakistan church

CNN's Ash-har Quraishi

ISLAMABAD, Pakistan (CNN) -- Five people, including two Americans, were killed and more than 40 others wounded Sunday in a grenade attack at a church in Islamabad, Pakistan.

CNN Correspondent Ash-har Quraishi surveyed the unsettling scene inside the church and reported the following from Islamabad:

QURAISHI: The attack occurred just after 10 a.m. local time in the Protestant International Church in Islamabad. Now, that's located in a diplomatic area considered to be very safe.

Two attackers apparently entered the church as services were being carried out there and threw a number of grenades at parishioners inside the church. Two of those detonated inside the church, injuring approximately 40 people and killing five.

Local authorities in coordination with the government officials that we've spoken to say that they've deployed military aid and crisis management teams as well as the various embassies involved.

Now, this is a church that is predominantly attended by diplomats, their families, children. And the injured that were from the church were taken to various hospitals.

Just a little while ago, we were allowed to go inside the church and see what had happened in there. A gruesome sight -- broken glass all over the place, chairs upturned. Inside the church where the services were being held, where it's believed that the grenades were detonated, blood on the floors, blood on the curtains as well as on the ceiling, which was about 30 feet high. It was a gruesome sight.

Investigators are still looking into who may have done this. There's been no claim of responsibility at this point. Pakistani President Pervez Musharraf offered his condolences to the families of those killed and those injured, saying that he is ordering the launch of a coordinated hunt to find the perpetrators of this attack, saying that these people are no friends of Pakistan.

CNN: This is a diplomatic area near the U.S. Embassy. How tight is security there and how many police officers are evident on a typical day? And how difficult would it be to stage an attack like this?

QURAISHI: Well, this is supposed to be one of the safest areas in Pakistan. The U.S. Embassy, as you said, is there. There are other various embassies there. The Chinese Embassy is there. This church, however, which is about 300 meters from the U.S. Embassy, has about three entrances.

Now, even having those three entrances, security is not very tight at this church as it would be expected to be. One guard, as we understand it, was there at the church, but apparently not enough people to guard the other two doors where these attackers entered from.

So it's supposed to be a safe area. It's considered a safe area. But apparently, guard was left down, and the attackers were able to strike.
