The head of MI5 has warned that young British men are heading to new terror training grounds in North Africa and the Middle East.
Arab Spring revolutions in Libya, Syria and Egypt have created unstable areas where al Qaeda can thrive, said Jonathan Evans, director-general of the security service.
The terror group is establishing itself in those countries after being disrupted in Afghanistan and Pakistan, he said.
“A small number of British would-be jihadis are also making their way to Arab countries to seek training and opportunities for militant activity, as they do in Somalia and Yemen.
“Some will return to the UK and pose a threat here. This is a new and worrying development and could get worse as events unfold.”
