The emerging trend of sticky bombs, as used in an attack on an Israel embassy car, is a bigger threat than improvised explosive devices (IED), the chief of elite National Security Guard (NSG) said Wednesday.

"The latest and bigger threat is the way in which the attack on Israel embassy's SUV was carried out," NSG chief R.K. Medhekar told reporters in Manesar on the sidelines of a seminar on "Emerging trends of Terrorism in India with special emphasis on defeating IED attacks".

He said terrorists have always chosen new and different styles of terror attacks but the use of magnetic bombs was a "serious matter of concern for security forces".
"Detection and defusing of bombs is the main part of the duty of peace keeping forces. To trace sticky bombs timely would be the greater challenge and the elite force had already started working in that direction."

"After the sticky bomb incident (in Delhi), we have issued new directions to our commandos."

NSG's bomb data centre is holding the three-day 12th international seminar at its main training centre in Manesar near here.

Some 23 members from various foreign countries are attending the seminar besides 103 Indian delegates from various security agencies of the country

The sticky or magnetic bomb that was used to target Israel embassy car injuring four people in a high security zone in Delhi Monday, is a small, furtive explosive known by many names at different places.

The easy-to-use device is fast becoming a preferred choice for many insurgent groups.

Only a month back, Iranian nuclear scientist Mostafa Ahmadi Roshan was killed when his car was blown up by a magnetic bomb in Tehran after two men on a motorcycle attached the explosive to his car.

Terror groups have used this type of explosive in Iraq and Afghanistan.
