Four policemen were killed and seven others wounded in double-suicide attacks on their checkpoint outside a security forces station in the southern Helmand province, said Gen Abdul Rahman Sarjang, provincial police chief in Helmand.
Sarjang said five insurgents equipped with suicide vests were shot and killed by security forces. Mohammad Rasoul Zazi, an army spokesman in Helmand, said one soldier was killed and another was wounded in the attack.
Meanwhile, another policeman was killed and four others wounded when their vehicle was hit by a roadside bomb in the southern Uruzgan province, said Rahimullah Khaliqi, the district administration chief.
Also today, the Afghan power company said it repaired some power supply cables from Tajikistan that were damaged during fights between Afghan security forces and insurgents.
The company said there were still power shortages in the capital of Kabul because their engineers couldn't work in some areas where gun battles continued to rage.
Kabul has been suffered from severe power outages in the past two weeks because battles between Afghan security forces against insurgents have disrupted power provided by Uzbekistan.
