Airbnb says it will host 20,000 Afghan refugees

Airbnb has pledged to provide free housing for 20,000 Afghan refugees.

CEO Brian Chesky said Tuesday that the program would begin immediately, and that Airbnb would pay for the stays. "The displacement and resettlement of Afghan refugees in the US and elsewhere is one of the biggest humanitarian crises of our time. We feel a responsibility to step up," Chesky said in a series of posts on Twitter.
