The United States urged itscitizensFriday to "immediately"leavethegatesaroundKabul'sairport, where a suicide bomber this week targeted crowds trying to flee Taliban rule.
Earlier Friday, the Pentagon said that the high-riskKabulairlift operation to evacuate Americans and Afghan allies still faced "specific, credible threats".
"UScitizenswho are at the Abbey gate, East gate, North gate or the New Ministry of Interior gate now shouldleaveimmediately," the US Embassy inKabulsaid in a security alert.
"Because of security threats at theKabulairport, we continue to advise UScitizensto avoid traveling to theairportand to avoidairportgates," the embassy said.
The alert gave no further details on what the security threats might be, but it followed Thursday's attack that killed scores of people including 13 US servicemen.
The blast claimed by the Islamic State jihadist group targeted US forces, but hit hardest the mass of people who had converged on theairportin a desperate bid to escape the Taliban's feared hardline rule.
