Muslim extremists want Pakistan
Faced with increasing violence and unrest, Pakistani President Pervez Musharraf declared a state of emergency Saturday, government sources told CNN.
President Pervez Musharraf has faced a flurry of criticism from opponents in Pakistan. Musharraf issued an order proclaiming the emergency and suspending the nation’s constitution, according to a statement read on state television, and declaring martial law.
Musharraf is scheduled to address the nation at 1800 GMT (2 p.m. ET) Saturday.
The Supreme Court declared the state of emergency illegal, claiming Musharraf had no power to suspend the constitution, Chief Justice Iftikhar Mohammed Chaudhry told CNN.
A senior Pakistani official told CNN that the emergency declaration will be “short-lived,” and will be followed by an interim government. Martial law is a way to restore law and order, he said.
Shortly afterward, Chaudhry was expelled as chief justice, his office told CNN. Troops came to Chaudhry’s office to tell him. The government appointed Justice Abdul Hameed Dogar as the new chief justice, according to state television.
It was the second time Chaudhry was removed from his post. His ousting by Musharraf in May prompted massive protests, and he was later reinstated.

Meanwhile, former Prime Minister Benazir Bhutto, who left Pakistan last week to visit her family in Dubai, arrived in Karachi on Saturday, according to her husband, Asif Ali Zardari. She returned to Pakistan last month, despite death threats, after several years in exile.
On October 18, upon her return, at least 130 people were killed when a suicide attacker tried to assassinate her. Bhutto was lightly wounded, but escaped largely unharmed.
