Riyadh: The results of laboratory tests for the remains of the suicide bombers, who blew themselves up in the terrorist attacks in Saudi Arabia during the past years, show heroin substances intended to make them not feel pain when they blow themselves up.

The Saudi, Al Watan newspaper quoted on Thursday the Saudi security advisor, Dr. Yusuf Rumaih that the Kingdom sent the samples of remains of those terrorists to three foreign countries, where the results showed the presence of heroin in their bodies.

This indicated that the drug led them to "commit suicide with indifference as they were promised paradise with virgins."

Rumaih said that the terrorists used sexual obsession to recruit the youth in addition to anesthesia and heroin to drug them.
