THESSALONIKI, Greece — A riot broke out late Wednesday at a migrant detention center in northern Greece, leaving two police officers injured and 30 migrants arrested, authorities said.

The facility where the unrest erupted was holding about 750 migrants of various nationalities, police said. Two officers were treated for injuries after being hit by a rock and bitten on the hand.

Greece this summer introduced one of Europe’s toughest migration regimes, allowing detention for up to 24 months and imposing prison terms of two to five years for illegal entry or stay. Under the stricter laws, migrants denied asylum face mandatory jail sentences.

Wednesday's clashes came a day after three migrants died and 55 were rescued near the southern island of Crete when a boat carrying them from Libya sank. Two of the rescued migrants, both from Sudan, were arrested on smuggling charges.

Arrivals from Libya to Crete have surged in recent months. But Migration Minister Thanos Plevris said earlier Wednesday that overall migrant arrivals had dropped compared with a year earlier.

He defended Greece’s tough migration laws and voiced support for proposals backed by other European Union members to establish dedicated deportation centers.
