At least six people have been killed by a bomb near the Danish embassy in Islamabad.
Nauman Malik, who works next door, told the BBC about the chaos of the moments after the blast.
There was a large noise and everything was literally rocked by the effects of the blast.
The blast damaged the embassy and nearby vehicles
I work in the building next door to the Danish Embassy.
When we looked out there was smoke all over the place and everything was shattered. Each and every car standing in the parking lot was destroyed.
There were screams all over the place and nothing else. People were running everywhere.
There were injured people, blood was all over the place, a few people were bleeding in front of me, and blood coming out of their heads.
It was terrible. It was like nothing ever before. I can't express it.
We had to run out without anything because it was all so sudden. We left the area and everything was just a complete mess.
There was smoke all over the place so we couldn't see anything. We had to leave the scene as safely and as quickly as possible.
The entire building was evacuated. It was underway when I left. Hopefully everyone will be out now. Phones were ringing all over the place.
The sounds of ambulances were there and there were sirens everywhere. My brother picked me up and I'm back home now and with my parents.
I never felt like this before.
