Prasad said that though the bomber blew the car at the embassy gates, the shockwaves could have brought down the building roof had the barrier not been there.

More than 40 Afghan citizens who had lined outside the embassy to seek visas had a miraculous escape as they were standing behind the hexa-barrier. But those outside the embassy were not so lucky and most casualties took place on the main road.

Eight of the 11 Afghan policemen stationed outside the embassy died on the spot. Eyewitnesses told The Indian Express that 10 women, including five from one family, died even as they were entering the embassy. According to Prasad, several children, who were walking to a school nearby, were also killed in the attack.

While the Indian toll has remained steady at four, the casualty figures of Afghan citizens has been rising sharply in the past three days. While the initial toll was 37 dead, Prasad said that as of Wednesday evening, at least 54 had been confirmed killed. The toll could rise — of the 139 admitted in various hospitals in the city, 61 were said to be in critical condition.

A major tragedy was averted as a busy shopping complex right next to the embassy escaped maximum impact, the hexa-barrier being the deflector.

“I was looking out at the embassy when the blast took place. I was blown into my shop by the impact. When I regained senses, there were body parts strewn all around. People were running around in panic but I was not badly injured,” said 18-year-old Ajmal Nasiri who works at a printing press next to the embassy.
