* TIRAH - Three militants from the Tehrik-e-Taliban Pakistan (TTP), or Pakistan Taliban, were killed in fresh clashes with another militant group, Lashkar-e-Islam, in the Tirah Valley of Khyber Agency, tribal sources said.

The two groups have escalated attacks against one another in recent days as part of a growing rivalry for control of Khyber, a strategic route into Afghanistan used by both Taliban militants and NATO supply trucks.

* BARA - A soldier was killed by a homemade bomb in an empty house during a clearing operation by Pakistani forces in the Bara area of Khyber, security officials said.

UCH - A group of militants ambushed a Pakistani paramilitary convoy in the Uch area of the southwestern Baluchistan province, security officials said. Three militants were killed when Pakistani forces returned fire.

Baluch separatists and Taliban militants are active in the province, and have been blamed for such violence in the past.

CHARSADDA - Unknown gunmen shot and killed a former local politician in Charsadda district, in the northwestern Khyber-Pakhtunkhwa province, police officials said.

Police officials said the man was a member of the Awami National Party (ANP), the provincial ruling party, which is often targeted by militants who see the ANP as supporting the U.S.-led war against al-Qaeda and The Taliban in Afghanistan.

No one has claimed responsibility. (Reporting by Gul Yusufzai in QUETTA and Jibran Ahmad in PESHAWAR)
