Islamabad  - At least eight people, including two terrorists, were killed and more than a dozen injured as a car bomb exploded in Pakistan's militancy-hit North West Frontier Province (NWFP) on Tuesday, a security official said.

"Six people we killed and 16 people were injured when a bomb fixed with a car parked at Bazid Khel locality of Peshawar, the provincial capital of NWFP, went off," said an intelligence official who spoke on condition of anonymity.

'The two terrorists tried to escape after the blasts but local people spotted them fleeing and shot them dead," Peshawar City Police Chief Iffat Ghayor told reporters. He also said that a young girl was among the victims of the blasts.

The blast occurred a day after the NWFP government signed a peace deal with pro-Taliban militants in Swat, an NWFP district which has seen a wave of violence since late 2007 when the follower of a radical cleric Maulana Fazlullah, who waged an armed campaign against the government for the enforcement of Taliban rule in the region.

Under the deal, the provincial government agreed to enforce sharia law in the six districts of the Malakand division, including Swat district of Hazara, in exchange of assurance for peace form the militants.

Meanwhile, United Nations' Resident Representative Fikret Acqura on Tuesday called on veteran Baloch nationalist leader Nawab Khair Bakhsh Marri to request him to use his influence for the safe release of UNHCR kidnapped chief John Solecki.

Solecki was kidnapped on February 2 from the south-western province of Balochistan by an unknown group hat identified itself as Balochistan Liberation United Front
(BLUF).

On Friday, the kidnappers set a 72-hours deadline to kill Solecki if their demand of setting free more than 140 female political prisoners and around 6000 of their colleagues was not met. The ultimatum was extended for "few days" on Monday.

Pakistan's government has denied the detention of any women and questioned the claim of thousand of prisoners in the province.

Balochistan is Pakistan's largest but most sparsely populated province, where local tribesmen have long been demanding political autonomy and greater share in profits from vast energy resources exploited in the area. They waged an armed struggle in 2005.

Following the Tuesday parleys between UN officials and Baloch leaders, a spokesman of Member Balochistan Rights Movement, Abdul Wahab Baloch, who was present during the talks, told media that Marri informed the UN that he would make his efforts for release of Mr. Solecki.

However, instead of condemning the seizure of UN official, Baloch said the incident helped to highlight the issue of Balochistan where Pakistan army was committing excesses against the freedom fighters. (dpa)
