KABUL, Afghanistan -- Militants attacked US troops patrolling in southeastern Afghanistan yesterday, killing one American soldier and wounding two with gunfire and rockets, the military said.
In other violence yesterday, Afghan soldiers clashed with police in the southern Zabul province and Afghan troops battled militiamen in the city of Kandahar, killing two, according to local officials.
The American patrol came under fire near Orgun, a town in Paktika province where US troops man a base close to the Pakistani border, spokesman Major Mark McCann said.
The two wounded soldiers were rushed to a medical facility at another base in neighboring Khost province, where they were in stable condition, McCann said.
''The patrol received small arms fire and RPG fire," McCann said. None of the soldiers was identified.
In Zabul province, Afghan soldiers exchanged fire with police, leaving several casualties and prompting US forces to step in to restore order, police and witnesses said.
The 90-minute gunbattle started after Afghan National Army troops disarmed police at a checkpoint and a bazaar in Qalat, the provincial capital, said deputy police chief Jailani Khan.
Khan asserted that the army had no authority to disarm the police. The fighting subsided after US forces took over security. He said there were some casualties, but he didn't know how many.
A shopkeeper who was reached by telephone from Kandahar said on condition of anonymity that he saw at least three bodies.
American helicopters were still circling above the city.
A US military spokesman confirmed there had been an incident in Qalat, but gave no details. Afghan army officials were not immediately available to comment.
Zabul is one of the most insecure provinces in the lawless reaches of southern and eastern Afghanistan, and has been the scene of heavy fighting in the past year between coalition forces and Taliban rebels.
The United States is helping to train the new national army, which is meant to gradually replace militia security forces usually loyal to local commanders.
In a third incident yesterday, Afghan army soldiers opened fire on provincial militiamen in the area of the Durai bazaar in Kandahar city, killing two of them and wounding one, said Khalid Pashtun, spokesman for the Kandahar governor. He said details of the clash were unclear and an investigation was underway.
Also, an ammunition depot at a compound used by Afghan army and US special forces in the city exploded late Sunday, wounding three Afghan soldiers, Pashtun said.
It wasn't clear what caused the blast. No US personnel were reported hurt.
