Winning hearts and minds
Thousands of Pakistanis have taken part in anti-American protests after an attack on a village near the Afghan border that killed 18 people.
The main demonstration was held in the main city of Karachi with protesters chanting "Death to America".
The missile strike apparently targeted al-Qaeda's deputy Ayman al-Zawahiri, who was said not to have been there.
US media say the attack was carried out by the CIA.
About 10,000 people rallied in Karachi, Pakistan's biggest city, chanting "Death to American Aggression" and "Stop bombing innocent people".
A leader in the coalition of anti-US Islamic groups that organised the nationwide protests said General Musharraf must step down.
"The army cannot defend the country under in his leadership," Ghafoor Ahmed told protesters in Karachi.
Reports citing unidentified Pakistani officials say the strike was launched on intelligence that Zawahiri had been invited to dinner in the village.
However, a senior intelligence official told Reuters news agency they had no evidence he was present at the meal.
