PESHAWAR, Pakistan, Oct 2, 2008 (AFP) - Taliban militants active in northwestern Pakistan are holding a Polish engineer who was kidnapped at the weekend, a militant spokesman said Thursday.

The Pole, identified as Piotr Stanczak, was kidnapped by gunmen on Sunday who shot dead his two drivers and a security guard in northern Attock district.

'He is with us. We have kidnapped him,' Mohammad, a spokesman for militants active in the troubled Darra Adam Khel region told reporters in the nearby northwestern city of Peshawar by telephone. He uses only one name.

There were no further details and officials have not commented on who they believe is holding Stanczak.

In August, Taliban militants kidnapped two Chinese telecommunication engineers from the restive Swat valley in North West Frontier Province.

The Chinese, working for Zhongxing Telecommunication Equipment, are still being held by the Taliban who were demanding the release of fellow militants from custody in return for their freedom, officials said.

The United Nations said on Thursday that it was pulling the children of its international staff out of Pakistan because of worsening security.
