European Union officials are warning of a potential new migrant crisis triggered by conflicts in the Middle East, particularly Iran, as the bloc struggles to implement its new migration agreement.

The European Union is bracing for another potential migrant crisis sparked by conflict in Iran, with EU Commission Chief Ursula von der Leyen warning of uncertain migration flows and the EU Agency for Asylum predicting that displacement of just 10% of Iran's 90 million population would create refugee movements of unprecedented magnitude, while the bloc's newly agreed Migration and Asylum Pact faces implementation challenges from Hungary and Spain.
