EU interior ministers will hold an emergency meeting Tuesday in hopes of bridging a deep rift over Europe's worst migrant crisis since World War II, a day after Hungary gave its army drastic new powers to protect its borders, AFP reports.

Tuesday's meeting will see ministers discuss controversial binding quotas to relocate 120,000 refugees around the bloc from frontline states after they failed to reach a deal last week, and ahead of a bloc-wide emergency summit opening Wednesday.

On the eve of the meetings, UN Secretary-General Ban Ki-moon appealed to leaders across the 28-nation bloc, urging them to "show leadership and compassion" as the continent grapples with the wave of migrants, many of them refugees fleeing the conflict in Syria.
