At least 34 people were killed on Sunday in two separate suicide bombings in Afghanistan that targeted a military base and a provincial chief, officials said.

There were no immediate claims of responsibility for the attacks, which took place as Afghan government representatives and the Taliban hold face-to-face talks in Qatar for the first time to end the country’s decades-long war.

In eastern Ghazni province, 31 soldiers were killed and 24 others wounded when the attacker drove a military humvee full of explosives onto an army commando base before detonating the car bomb, according to an official in Afghanistan’s National Security Council, who spoke anonymously because he was not permitted to speak directly to the media. Ghazni’s provincial health department chief, Zahir Shah Nikmal, also confirmed the death toll and casualty figures from the attack.

Afghanistan’s Defense Ministry released a statement claiming 10 soldiers were killed and nine wounded. The ministry also offered a different account of what happened than the official at the National Security Council, saying the vehicle exploded near the army base after security forces opened fire on the car. It was not immediately clear why there was a discrepancy.

Interior Ministry spokesman Tariq Arian said a suicide bombing took place, though he did not provide further details. The soldiers stationed at the base were responsible for conducting night raids, providing support to the army and police forces under siege, and taking part in large-scale operations against the Taliban and Islamic State group in eastern and southern provinces of Afghanistan.
