Abdul Hay Mutmaeen, a spokesman for the Taleban when they ruled Afghanistan, was among those arrested in operations Thursday night in two villages in Andar district of the eastern province of Ghazni, district chief Sher Khan Yosoufzai said.

The international military force in Afghanistan says it has captured more than 100 senior Taleban figures since April in near-nightly raids targeting the top leaders.

However, the successes have not managed to reduce insurgent attacks.

In Kandahar in the south, a joint Afghan and coalition force captured a senior Taleban commander who directed the movement of fighters and equipment through Nad Ali district in Helmand province, NATO said. The Thursday night operation came a day after a joint force captured a Taleban logistics officer for networks operating in Kandahar city, the coalition said.

In the east, Afghan and coalition forces captured an insurgent suspected of making bombs Thursday night in Behsud district of Nangarhar province.

The security force targeted a compound outside the provincial capital Jalalabad in pursuit of the man, and Afghan forces used a loudspeaker to call for all occupants to peacefully leave the buildings. After the occupants were interviewed, one of them led the security force to a different compound where the bomb-making suspect was apprehended.

On Monday, Afghan and coalition forces killed five insurgents and detained five more near Tatang in Nangarhar province. The combined force found multiple automatic weapons along with dozens of rocket propelled grenades and boosters, hand grenades and 2,000 rounds of ammunition.

NATO also reported that an Afghan intelligence unit found materials in a rock quarry in the Spin Boldak district of Kandahar that could have been used to make more than 100 roadside bombs. The cache discovered Thursday night included 1,900 kilograms of ammonium nitrate, more than 5,400 electronic fuses, 3,200 meters of detonation cord and 275 kilograms of black powder.
