Islamabad: A joint investigation into the suicide bombing that led to the death of Pakistan's surgeon general on Monday was launched by security agencies on Tuesday.

The full fledged investigation into the assassination of Lt. General Mushtaq Baig has a team of senior officials of the Federal Investigation Agency, the police and the army working on it, according to Interior Secretary Kamal Shah.

The possibility of foreign involvement will also be explored.

Baig was killed Monday when a bomber blew himself up next to his car after it stopped at a traffic light on a busy road in Rawalpindi, a city just south of the capital, Islamabad.

So far the government has only blamed people who were "damaging the cause of Islam," a reference to religious extremists.

This is the latest in a string of attacks in Pakistan, which is in the process of defining its new government.
