Islamic State fundamentalists have claimed responsibility for the attack in the Indonesian capital in which seven people died, including two civilians.

Twenty others were injured, as police fought a gunfight with attackers.

Briton Hunnisett, 49, was in one of the shopping malls targeted by the terrorists just moments before the attacks unfolded – which included a multiple suicide bomb attack outside a nearby café.

"I was very lucky," Hunnisett told Motorsport.com. "I was there five minutes before the attack.

“I was inside the mall, at exactly the point of one of explosions and I just avoided it. When I realised what happened inside the mall, I thought I was a lucky man.

“[It] was a tough day for all of us, but we must keep looking forward without any fear."

Hunnisett has long been involved in motorsport in the region after the end of his own junior single-seater career.

His long-term protege Haryanto is believed to have $15million from the Indonesian government to land a drive with Manor this year, and tested for the team in Abu Dhabi at the end of last year.
