Pakistan: Key Islamic scholar shot
From CNN Producer Syed Mohsin Naqvi
ISLAMABAD, Pakistan (CNN) -- An angry mob has set fire to several buildings in downtown Karachi while others threw stones at Pakistani forces, hours after unknown assailants shot and killed a well-known Islamic scholar known for his preaching against American foreign policy, according to police.
Paramilitary police fired on protesters who threw stones, wounding one person, police said.
Hours earlier, a group of gunmen opened fire on a vehicle carrying Mufti Nizamuddin Shamzai outside his home, killing the cleric instantly, according to officials at the Binori "madrasa" -- or Islamic school -- where he taught.
His son, driver and bodyguard were also shot and wounded in the attack. They are in stable condition.
The motive of the attackers is not clear.
Although Shamzai was known for criticizing U.S. policy in Iraq and Afghanistan in recent months, he was not known to be involved in politics or sectarian issues.
Protesters immediately took to the streets, after learning of the shooting.
The mob burned at least 10 buildings -- including a police station -- and many police cars. Police closed off all the main roads in the port city.
Police investigators have not inspected the scene of the shooting, for fear sparking more violence, a Karachi police official said.
They also cannot reach the buildings that were set on fire.
The protesters have taken Shamzai's body to the Binori madrasa, where his students have gathered for a funeral planned for later in the day.
