Taliban tightens grip on Kabul airport as thousands of Americans await evacuation

The Taliban were still tightening their grip on Afghanistan's capital city on Wednesday, with the militants controlling access to Kabul's airport. While U.S. nationals have reported being unable to get to the runway for scheduled evacuation flights, those flights were continuing to take off, carrying Western diplomats, workers and their families — and Afghans who've helped them — out of the country.

CBS News correspondent Roxana Saberi and her team were among those who got out overnight on a U.S. cargo plane that brought them to Doha, Qatar, in the Persian Gulf. She and her crew were on the plane with about 300 Afghans who fled the Taliban, most carrying little but hope, and relief.
