Afghan officials say militants have attacked an army base in the southern province of Kandahar, killing at least 10 soldiers and wounding nine.
The Defense Ministry said the attack began just before midnight on May 22 at Camp Achakzai in the Shah Walikot district.
Ministry spokesman Dawlat Wazeri said that at least 12 attackers were killed in a battle that lasted several hours overnight.
The Taliban and other militants have stepped up attacks in recent weeks in Afghanistan.
Afghan security forces are battling a 16-year-long insurgency led by the Taliban, an extremist group that was driven from power after a U.S.-led invasion following the September 11, 2001, terror attacks on the United States.
The United States is considering whether to send 3,000 to 5,000 more military advisers to help train and assist Afghan security forces.
