(Adds attacks in two other provinces)
KABUL, Aug 5 (Reuters) - An Afghan army soldier opened fire on international and Afghan forces at a British military training academy in Kabul injuring a number of them, the Ministry of Defence said on Tuesday.
"Today at 12 pm, a terrorist in army uniform opened fire on international partners and other Afghan officers, wounding several," the statement said.
The U.S.-led coalition in Afghanistan confirmed only that there had been an incident between Afghan and foreign troops at the facility.
Modelled on Sandhurst, a military academy in Britain, the facility's opening late last year was marred by another insider attack that left two injured.
Such attacks have eroded trust between the allies and complicated efforts to train Afghanistan's new 350,000 strong security force.
In a second, similar attack on Tuesday, several were wounded in eastern Paktia province when a policeman opened fire on international and Afghan forces, police chief Zalmay Oryakhil told Reuters.
The Taliban claim insider attacks reflect their ability to infiltrate the enemy, while ISAF officials say the incidents often arise over misunderstandings or altercations between troops.
In 2012, dozens of incidents forced international troops to take measures to reduce interaction with their Afghan partners and since then, the number of insider attacks has fallen sharply.
Adding to the tensions between the allies on Tuesday, a NATO airstrike hit a vehicle carrying civilians in western Herat province, local officials said, killing four members of one family including two children.
"We strongly condemn the killings by foreign troops and we have reported this to the presidential palace," deputy provincial governor, Aseeluddin Jameh, told Reuters.
"The family was coming back from a wedding in Shindand district when they were hit."
