(KARACHI, Pakistan) -- Police and rescue officials confirm four people are dead, and several others injured, after two explosions went off at a Sufi shrine in Karachi, Pakistan on Thursday.
Police officials at the scene say it's too early to tell whether or not it was a suicide attack.
The explosions happen at a time when Pakistani President Asif Ali Zardari is visiting Karachi and living in his private residence not far from the explosion site.
Police, however, say the target was the shrine, since the explosions took place at the shrine's entrance. The shrine is a famous landmark in Karachi that's especially busy Thursday evenings.
In the past, terrorists have targeted Sufi shrines in Lahore. This week, they have also killed a religious leader in a spree of target killings in Karachi.
