At least one person was killed and more than 60 people were injured when a suicide bomb exploded on Wednesday outside the United States' main military base of Bagram in Afghanistan, local and NATO officials said.

U.S. Secretary of State Mike Pompeo condemned this suicide bombing on the press conference Wednesday.

"Initial reports show that there were at least five coalition troops injured in the attacks," he said.

The explosion occurred at 5:50 a.m. local time on Wednesday when militants detonated a massive car bomb and seized a building outside the U.S. military base.

Local media said militants also fired rocket propelled grenades (RPGs) onto the Bagram base.

The attack was "quickly contained and repelled" and there were no U.S. or coalition casualties, but a medical base being built for locals was badly damaged, Resolute Support, the NATO-led mission in Afghanistan, said in a statement.

No organization or individual has yet claimed responsibility for the attack.

Located in Bagram district of eastern Parwan province, the Bagram military base, some 50 kilometers north of Afghan capital of Kabul, has been serving as the main U.S. and NATO military base in Afghanistan for the past 18 years.

The attack comes as Washington resumed stalled peace talks with the Taliban on Saturday.
