A suicide bomber blew himself up at a Pakistani security post in the Swat valley today killing five soldiers, while eight militants were killed in a clash, in the most serious violence in the area for weeks.
The military went on the offensive in the region northwest of the capital in late April and has killed or driven out many Taliban militants in what has been widely seen as a successful operation.
The army push has allayed fears among allies, in particular the United States and other countries with troops in neighbouring Afghanistan, that nuclear-armed Pakistan was failing to get to grips with spreading Islamist violence.
The car-bomb attack in Khawazakhela, about 14 km north of Swat's main town of Mingora, raised concern that the Taliban could make a comeback, especially as no top insurgent leaders in the former tourist valley were killed or captured.
"The bomber rammed his explosive-laden vehicle into the post," said a senior military official in the region who declined to be identified. Five men were killed and four were wounded.
The attack came a day after hundreds of people, including many women, attended a music and dance show to celebrate Independence Day in the valley, where the Taliban had banned music and girls' education.
In a separate incident, eight militants were killed in a clash that erupted as soldiers searched another area, the military said.
Pakistan's efforts to suppress militants on its side of the border are vital for a US-led bid to stabilise Afghanistan, where Taliban have threatened to disrupt an August 20 presidential election.
US envoy to Afghanistan and Pakistan, Richard Holbrooke, was due in Pakistan later on Saturday.
