No U.S. or coalition casualties were reported after the attack.

A suicide bomber struck an under construction medical facility in Bagram, the largest U.S. military base in northern Afghanistan, Wednesday morning, with the Taliban claiming responsibility for the attack, Afghan and U.S. officials said.

Two car bombs were involved in the attack, which was followed by a gun battle between the attackers and local security forces, killing at least one person and injuring at least 65 more, according to the Bagram district governor.

There were no casualties to U.S. and coalition forces, according to U.S. military officials.

The Taliban have now claimed responsibility for the attack.

A number of nearby civilian houses were destroyed in the bombing, according to the local member of parliament for Parwan province where Bagram base is located. Around seven attackers are believed to have been involved in the attack, with two attackers killed by Afghan security forces, he added.

The explosion at the site of the medical facility was “huge,” according to the Parwan police chief.

The area has been cordoned off by the U.S. military, although the security operation is still ongoing.

The Taliban’s claim of responsibility comes as the U.S. announced that they had reopened negotiations with the group after talks broke down in Doha, Qatar. President Trump had described the peace talks as “dead” in September.

“The US rejoined talks today in Doha,” a U.S. State Department official said Saturday. “The focus of discussion will be a reduction of violence that leads to intra-Afghan negotiations and a ceasefire.”

Trump visited Bagram air base in a surprise visit on Thanksgiving this year, in what was his first trip to the country.

When asked if the U.S. had restarted peace talks with the Taliban, he replied with “yes,” but did not offer more details.
