As many as 140 Afghan soldiers were killed on Friday by Taliban attackers apparently disguised in military uniforms in what would be the deadliest attack ever on an Afghan military base, officials said.
One official in the northern city of Mazar-i-Sharif, where the attack occurred, said on Saturday at least 140 soldiers were killed and many others wounded. Other officials said the toll was likely to be even higher.
The officials spoke on the condition of anonymity because the government has yet to release official casualty figures.
The Western-backed Afghan government is locked in a prolonged war with Taliban insurgents and other militant groups.
The attack was launched near a mosque on the base in Mazar-i-Sharif, the capital of Balkh province, as soldiers were leaving Friday prayers, said army spokesman Nasratullah Jamshidi.
Six attackers in two military vehicles told guards at the gates that they were carrying wounded soldiers and urgently needed to enter, he said.
After killing at least eight soldiers and wounding 11 others with rocket-propelled grenades and guns, one attacker was killed and the other five arrested, Jamshidi said.
A number of German and other foreign soldiers are based in Mazar-i-Sharif, including about 70 who advise the corps headquarters as part of a Nato-led multinational mission to advise and train the Afghan security forces.
“To our knowledge, no Germans were affected. Nor were any other soldiers in the multinational force harmed,” said a spokesman for the German Operations Command. The statement was echoed by American officials.
Taliban spokesman Zabihullah Mujahid said the attackers had set off an explosion, allowing suicide bombers with small arms to breach the base’s defenses.
“Our fighters have inflicted heavy casualties on the Afghan army stationed there,” he said.
The base is the headquarters for the Afghan National Army’s 209th Corps, responsible for much of northern Afghanistan, including Kunduz province where there has been heavy fighting of late.
The Nato command in Kabul called the attack “murderous and reprehensible.”
