MI5 are understood to be hunting for a Syrian scientist posing as a refugee plotting a chemical attack on a British seaside town.
Counter-terrorism police raided a migrant center in Berlin the day after the Christmas market truck massacre and are said to have recovered documents detailing the planned attack.
They allegedly contained detailed of various chemical agents and included the name of two English towns.
The Muslim terrorist, said to be in his early 30s, has gone off the radar and it is feared he could be in the UK, according to the Sunday Express.
It came after a raid of Tempelhof airport, which has now been closed down to house the country’s largest refugee camp.
Officers visited the site on December 20, and a source told the Express the documents recovered were so serious that MI5 were immediately called in.
It is thought officers are searching both named targets, and one of them is described as a ‘seaside town on the south coast’.
Potential targets could include Brighton and Hove, Dover, Bournemouth or Torquay.
US authorities have been following the terrorist since he left Damascus and it has been claimed British officials were told previously about a Syrian scientist posing as a migrant.
The paper claims the scientist went rogue having been a a vital cog in President Assad’s chemical attacks.
