Investigators probing the explosion of a Israeli diplomat's car on Wednesday said preliminary forensic examination of the blast material showed traces of potassium chlorate and nitrate.

Officials monitoring the probe said that the quantity of explosive material used in the probe was very less.

According to the preliminary forensic report of the Central Forensic Science Laboratory, the explosion was only able to create a loud noise and dent the body of the SUV and not rip it off as otherwise it could have been fatal.

The triggering mechanism was not clear as yet to the experts.

An Israeli mission car carrying Administrative Attache Tail Yoshi, wife of a Israeli Defence Attache, was injured on February 13th when terrorists stuck a magnetic bomb to her car in high-security Aurangzeb road.
