Pakistan's prime minister vowed to stop any "foreign power" from violating the country's borders as millions of people celebrated 60 years of independence on Tuesday with parties, fireworks -- and much introspection.
"I want to make it clear that not under any circumstances will we allow any foreign power to enter Pakistan's territory," Prime Minister Shaukat Aziz said at a traditional flag-hoisting ceremony in the capital Islamabad to mark Independence Day.Aziz's comments came amid signs of growing unease in Pakistan over questions in the United States whether President Pervez Musharraf's government was doing enough to battle al Qaeda and pro-Taliban militants on its border with Afghanistan.
Some U.S. politicians recently said the United States must be willing to strike al Qaeda targets in Pakistan even without Islamabad's permission -- drawing rebuke in the country.
President George W. Bush also signed into law a bill requiring him to confirm Pakistan's progress in fighting Taliban and al Qaeda before releasing future aid, disturbing many Pakistanis sensitive to what they see as excessive U.S. demands.
The controversy added to a difficult time for Musharraf, who faces major problems securing a second term with allies wavering, approval ratings slumping, a Supreme Court that might uphold constitutional challenges, and rising Islamist violence.
The extent of Musharraf's problems were shown this month by reports the president had considered declaring a state of emergency.
In past years, streets in Islamabad would have been festooned with flags and illuminations. But because of the chronic security situation, it has become a low key affair in the capital.
Paramilitary troops were on standby to maintain order. Police checked vehicles in and around Islamabad, where two suicide bombings killed at least 26 people last month.
Pro-Taliban militants have stepped up attacks across Pakistan, mainly in the conservative northwest tribal region, after a bloody military assault last month on Islamabad's Red Mosque to dislodge a pro-Taliban movement based there.
