Details are sketchy right now, but the Pentagon has acknowledged that an American soldier was killed on Monday in Afghanistan. The Taliban have already taken credit for a roadside bombing in northern Kunduz province, where they claim the attack took place. They also tweeted a picture of the killed soldier’s ID card.

The Pentagon doesn’t release any information for 24 hours until the next of kin can be notified. This death raises the death toll for U.S. troops to 20 for this year — there have also been three non-combat deaths. This makes 2019 the deadliest year for U.S. troops in Afghanistan since major combat operations were ceased in 2015. More than 2,400 troops have been killed in Afghanistan since the U.S. entered the country in 2001 after 9/11.

The Taliban claim that another American soldier and an Afghan soldier were seriously wounded in the roadside attack. 

Taliban spokesman Zabihullah Mujahid took to WhatsApp and social media to post that the U.S. soldier was killed in the Chardara district in northern Kunduz province as American and Afghan forces were carrying out a joint operation. Mujahid said that the roadside bomb that killed the service member had been planted by the Taliban.
