BRUSSELS (AFP) - Nato head Jens Stoltenberg warned on Monday that fighters from Islamic extremist groups may hide among the flood of migrants seeking refuge in Europe, increasing the need for an effective response.
Stoltenberg's comments came as he attended a meeting of European Union (EU) foreign and defence ministers which was set to approve the bloc's plan for a naval operation to tackle people smugglers operating mainly out of Libya.
"First of all this is a human tragedy, people are losing their lives trying to cross the Mediterranean," Stoltenberg said when asked about reports the Islamic State in Iraq and Syria (ISIS) militant group was trying to smuggle fighters into Europe by hiding them on migrant boats.
"Of course one of the problems is that there might be foreign fighters, there might be terrorists trying to hide, trying to blend in among the migrants," he added. "And this underlines the importance that we have to respond to this turmoil."
Western officials often use the term foreign fighters to describe people from Europe and the Middle East who have travelled to fight with ISIS.
Stoltenberg cited Nato's own efforts to work with countries in North Africa and the Middle East to tackle the root causes of the migrant problem.
But he stressed that the US-led military alliance was not for the moment taking part in the EU's unprecedented naval mission, which follows a series of deadly shipwrecks of migrant boats in the Mediterranean.
Stoltenberg said that so far, the 28-nation EU had not asked for help from Nato but the alliance was "ready to help if there is a request".
