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. The company will work closely with NGOs and its nonprofit arm, Airbnb.org, which provides housing to people in need following natural disasters and other crises. Tens of thousands of people have been attempting to leave Afghanistan in recent days after the country’s capital, Kabul, fell to the Taliban. Many Afghans have come to the airport in Kabul in hopes of departing on evacuation flights operated by the United States and other governments. “I hope this inspires other business leaders to do the same. There’s no time to waste,” Chesky said.
