US airlift evacuates US citizens and staff from Yemen

US Air Force transport planes began landing at Sanaa airport Tuesday to urgently evacuating US citizens after the US State Department Tuesday urged US citizens living in Yemen to leave immediately due to “extremely high” terrorist threats.” Non-emergency US personnel, including diplomats, were evacuated, followed by British embassy staff. This step indicates a sharp escalation in the far-reaching terror alert in force across the Muslim world since last Thursday.
