Europe is taking the wrong approach to fighting terrorism, former French Prime Minister Dominique de Villepin has told CNBC.

Speaking immediately after a series of explosions rocked the Belgian capital of Brussels, de Villepin said that they were "tragic events" but added that Europe should be showing that it is sticking to its rule of law and can only "reduce" the threat of terrorism.

"I do believe that our strategy should be very different than the one it is. Much less a military approach than a political approach, trying to find solutions in the Middle East and we are far from doing that," he said.

A series of deadly explosions hit Brussels on Tuesday. Belgian Prime Minister Charles Michel told a news conference that terrorists had committed murder in Zaventem Airport as well as at the Maelbeek metro station. He labelled it a cowardly attack and said it was a black day for Belgium.
