FBI age progressed pictures show what the Pan Am hijackers who killed 20 in 1986 terror outrage look like now

The FBI has used age-progression technology to create new photos of the four alleged Pan Am 73 hijackers.

The release of the photos came as the FBI launched a renewed hunt for the attackers behind the 1986 hijacking in Karachi, Pakistan that left 20 people dead.

The deadly hijacking took place on September 5 in 1986 that year when the attackers took control of Frankfurt-bound Pan Am flight 73 for 16 hours during a stopover in the southern port city.
