Security alert plane lands safely
RAF Tornados were scrambled
A plane has landed safely at Stansted Airport in what was believed to be a security alert.
An unspecified number of RAF planes were scrambled after Olympic Airways flight OA411 from Athens to New York asked to be diverted to Stansted.
It landed at 1529 GMT and the RAF planes have now returned to base after the incident was concluded 'safely', according to the MOD.
Essex police and fire services were in attendance at the airport.
'Full emergency conditions'
A spokesman for Stansted Airportsaid the plane landed under "full emergency conditions."
The BBC's Athens correspondent Richard Galpin told BBC News 24 the incident happened after an elderly man called a Greek newspaper anonymously and told them there was an bomb on board.
The paper called the police, who called the airline. No code word is believed to have been used.
The plane, which was carrying 290 passengers, landed safely.
The RAF is not releasing any more details of how many of its planes were involved for security reason.
