The United States embassy in Kabul is urging Americans to immediately leave the area around the airport in Kabul.
"Due to a specific, credible threat, all U.S. citizens in the vicinity of Kabul airport (HKIA), including the South (Airport Circle) gate, the new Ministry of the Interior, and the gate near the Panjshir Petrol station on the northwest side of the airport, should leave the airport area immediately," the embassy urged.
"U.S. citizens should avoid traveling to the airport and avoid all airport gates at this time," the embassy added, in bolded typeface.
Earlier on Saturday, President Joe Biden had warned that another bombing at the airport was "likely."
