BRUSSELS (Reuters) - EU leaders have made progress in negotiations with Turkish Prime Minister Ahmet Davutoglu on Monday and could still reach a deal on curbing migrant flows overnight, a senior official in the EU's executive said. "Good progress in difficult European Council talks on solving the refugee crisis," tweeted Martin Selmayr, chief-of-staff to European Commission President Jean-Claude Juncker. "A breakthrough during this night is possible." (Reporting by Alastair Macdonald; Editing by
