By Robin Emmott and Francesco Guarascio BRUSSELS (Reuters) - EU leaders will agree on Thursday to take in 40,000 asylum-seekers from Italy and Greece to confront a growing migrant crisis in the Mediterranean but delay a decision on how to share them out, according to a draft final summit statement. Stung by the deaths this year of almost 2,000 migrants trying to reach Europe by boat, the European Union has promised an emergency response but not national quotas for housing people fleeing war and poverty in Africa and the Middle East. Governments will agree to "...the relocation over two years from Italy and Greece to other member states of 40,000 persons in clear need of international protection, in which all member states will participate," according to a draft seen by Reuters.
