A suicide bomber killed two police guards today as they stopped him trying to enter the home of a government minister.
Police said four other people were wounded in the explosion at the front gate of the house belonging to Minister for Political Affairs Amir Muqam in the northwestern city of Peshawar.
The minister was in his home at the time but was unhurt, although his brother was wounded.
Elsewhere, a roadside bomb killed two paramilitary soldiers and wounded at least five in the northwestern valley of Swat, where Islamist militants are trying to impose Taliban-style rule, an army spokesman said.
Swat, which lies close to Pakistan's lawless tribal belt bordering Afghanistan, has seen a surge in violence since a militant cleric called for holy war after an army assault on a radical mosque in the capital, Islamabad, in July.
