"I said that migration would be one of our priorities," Brasseur said at a press conference prior to the spring session. "Now we'd really need to have real solutions," she stressed.
The five days of discussions in Strasbourg, France, are expected to be dominated by human rights issues. The meeting comes a day after a boat carrying between 700 and 950 migrants from Libya capsized and sank in the Mediterranean. Only 28 people have been rescued.
The Mediterranean is one of the main routes for migrants fleeing conflicts in North Africa and the Middle East. The United Nations estimates that at least 3,500 people died crossing the sea in 2014. The recent capsize could drive up the death toll for 2015 to about 1,600.
