President Joe Biden touted on Sunday the surging number of Afghanistan evacuations carried out so far by the United States, but acknowledged that such a massive operation does not come “without pain and loss.”

The White House said that the U.S has evacuated 30,300 people out of Afghanistan since Aug. 14, including more than 13,000 people over the weekend. That brings the total evacuated by the U.S. to about 35,500 since July, though the president stressed in a televised address that “we have a long way to go, and a lot could still go wrong.”
