Two suicide attacks in eastern and western Afghanistan killed two Afghan security personnel and wounded 12 others, officials said Thursday.

A suicide bomber with explosives strapped to his body attacked the provincial police headquarters Thursday in southeastern province of Paktika, killing one policeman, the interior ministry said in a statement.

Ten other policemen were wounded in the attack in Shrena, the provincial capital, the statement said.

The attack came a day after eight suicide bombers equipped with assault rifles stormed three government buildings in Kabul, killing at least 26 people, including 10 security personnel, and wounding more than 50.

Another suicide bomber attacked an Afghan army convoy Wednesday in the southwestern province of Nimruz, killing one Afghan soldier and wounding two, the defence ministry said.

Since 2003, Taliban militants have been mounting frequent suicide and roadside bombings as part of their campaign to topple the Western-backed Afghan government and expel around 70,000 international troops from the country.

Although most Islamic clergymen around the world denounce suicide attacks, the Taliban and other fundamentalist Islamic groups allow it under their own interpretations of the religion.

The rebel group were responsible for more than 120 suicide bombings in Afghanistan in 2008.
