Brussels: Europol`s director says terror cells are still actively plotting attacks against Europe.
Robert Wainwright, director of the European police organisation, said a drop in attacks, coupled with intelligence that had thwarted major plots, masked the ongoing threat.
His remarks on Thursday come amid news of a terror threat against Britain, France and Germany. The threat was intercepted in Pakistan by US intelligence officials, sparking a surge in drone missile strikes near the border with Afghanistan.
Wainwright was speaking at a security conference in Brussels.
Officials at the conference also warned of security threats coming from African countries.
Ronald K Noble, Interpol`s Secretary General, says a rise in drug trafficking had fuelled violence and instability. More than a quarter of all cocaine now passes through Africa from South America.
