For the first time after leaving Afghanistan earlier this month, United States has facilitated the exit of four American citizens from the war-torn country using an overland route to a third country, according to US media reports citing an official of the United States State Department.

Even though the names of those who departed Afghanistan are not known, United States House of Representatives member Markwayne Mullin revealed that the group consisted of one woman and her three children.

Mullin, a member of the Republican party and lawmaker from Oklahoma, said that the Americans who exit Afghanistan belonged to Amarillo, Texas.

"Our Embassy greeted the Americans as they crossed the border into the third country", the official from the United States State Department said, according to reports from CNN.

The woman, along with her family, was unable to get out of Afghanistan from the Hamid Karzai Airport in Kabul while the United States forces were evacuating and conducting airlift operations.

Representative Mullin said that the group spent more than 12 hours at a checkpoint maintained by the Taliban near the border and were able to leave at first.

The news comes as United States Secretary of State Antony Blinken stepped foot in Qatar, where the country has set up the new embassy after evacuating from Afghanistan. 

Blinken's trip to the gulf is aimed at gaining international consensus to evacuate Americans and at-risk Afghans, according to reports from Reuters.

The resettlement policy of the United States includes connecting airlifted families from Afghanistan to organisations that work on assisting refugees to help them kick off their new lives in the United States. The White House wrote in a tweet earlier this week, "Our goal is to safely and efficiently welcome these allies and vulnerable Afghans, while taking all appropriate safety and public health measures."
