Afghan police have killed seven Taliban insurgents in different provinces within one-day operations, as the security forces continue to press the militants, the country's Ministry of Interior said Tuesday.

"Afghan National Police (ANP) in partnership with the army and the NATO-led coalition forces conducted nine cleanup operations in Kabul, Kunduz, Wardak, Logar, Khost and Helmand province over the past 24 hours, killing seven armed Taliban insurgents," the ministry said in a statement.

The ANP also found weapons besides defusing five Improvised Explosive Devices (IEDs) as a result of the operations, it said.

Up to seven insurgent were wounded and four others detained by the ANP during the above raids, it added.

The Taliban insurgent group, which has been waging an insurgency of more than one decade, has yet to make comments.

In addition, three Taliban were killed when Afghan police and army responded to a Taliban attack against checkpoints in Duhab district in Nuristan province 180 km east of capital city of Kabul early Tuesday morning, provincial police chief Ghulam Ullah told Xinhua.

The Afghan forces and some 100,000 coalition troops have intensified cleanup operations against Taliban and other militants recently but the insurgents in retaliation responded by carrying out suicide and IED attacks.

Taliban on Monday carried out a suicide car bomb attack against a US company named "Contract" in charge of providing military and logistic services to security forces, killing two local employees and wounding 15 other civilians in eastern Kabul.
