US and UK pull staff out of Yemen amid terror alert

The US and UK governments have withdrawn diplomatic staff from Yemen and urged their citizens to leave amid concerns over security threats.

It follows the sudden closure of 20 US embassies and consulates on Sunday.

This was prompted by intercepted conversations between two senior al-Qaeda figures, including top leader Ayman al-Zawahiri, US media said.

The Pentagon said the US Air Force was flying workers out of the capital, Sanaa, on Tuesday morning.
