The United Nations has apologized for "a significant lapse in judgement" after photographs surfaced online showing some of its officials posing for photographs in front of a Taliban flag. The picture was taken in Afghanistan during a visit by Deputy Secretary-General Amina Mohammed this week to the war-torn country when she met the de facto authorities and expressed alarm over women's rights violations. As Mohammed was meeting the group's leaders, photographs of the UN personnel in front of the Taliban flag drew criticism. Watch this video for more details.
