There are chaotic and harrowing scenes at Kabul airport as civilians and foreign nationals try to flee Afghanistan, now controlled by the Taliban. At least five people have reportedly been killed at the airport, where foreign military troops are attempting to repatriate their citizens and Afghan nationals who've worked with them. Meanwhile, US President Joe Biden has spoken publicly for the first time since Kabul fell yesterday, saying he stands squarely behind his decision to withdraw US troops after 20 years. But he has admitted the situation there now has unfolded more quickly than he expected. A New Zealand Hercules aircraft and 40 defence force troops are preparing to depart to extract the more than 50 New Zealand citizens in Afghanistan. Susie Ferguson speaks to two people who've been amid the unstable and escalating Taliban takeover. Samantha Mort is Chief of Communications in Kabul for UNICEF Afghanistan, and journalist Lynne O'Donnell who was on the last commercial flight out of Kabul, before the airport closed to commercial airlines.
