Attaching a bomb to a car poses a new problem for security forces, police said today. Referring to an attack on a diplomatic car of the Israeli embassy in New Delhi on February 13, Kiran Bedi said law enforcement agencies worldwide will have to work together as a global village as such incidents are “cause-related and not country-specific.” A motorcyclist attached a magnetic device to the car while it was waiting at a traffic signal and a few seconds later it exploded, injuring four people, including the wife of Israel’s defense attaché. Federal Home Minister P Chidambaram said the diplomat's wife was apparently the target but refused to name any terror group for carrying out the strike.
