LONDON - Al-Qaida militants are using the countries which toppled their leaders in the Arab Spring as bases to train radical Western youths for potential attacks on Britain, the chief of the MI5 Security Service said on Monday.

In his first public speech for nearly two years, Security Service Director General Jonathan Evans said the Arab Spring revolts in Tunisia, Libya, Yemen and Egypt offered long-term hope of a more democratic Middle East.

But Britain's domestic spy chief said al-Qaida, which moved to Afghanistan from Arab countries in the 1990s and thence to Pakistan after the fall of the Taliban, was once again trying to gain a foothold in the Arab world.
