Benazir Bhutto addresses a news conference at her residence in Karachi, 03 Nov 2007

Former Pakistani Prime Minister Benazir Bhutto has called General Pervez Musharraf's decision to impose emergency rule a coup.

In an interview with CBS News Face the Nation on Sunday, Ms. Bhutto said Saturday's move was General Musharraf's "second coup" - referring to his 1999 overthrow of then Prime Minister Nawaz Sharif.

Ms. Bhutto also said she is deeply concerned that extremists in Pakistan will try to manipulate the volatile situation.

The twice-serving former prime minister says her opposition party, Pakistan Peoples Party will protest what she has called "martial law."

Shortly after emergency rule was imposed Saturday, Ms. Bhutto said she would meet with other political leaders to discuss a strategy for reversing General Musharraf's suspension of the constitution.

Ms. Bhutto returned to her homeland from self-imposed exile in mid-October as the first step towards a power-sharing deal with the president, who has lifted old corruption charges against her.

But since her return, Ms. Bhutto has become a fierce critic of the government and its handling of the October 18 attack that killed 139 people at her homecoming motorcade in Karachi.
