The leader of Malta says his island nation is working to solve the case of a German-run rescue ship stuck in international waters with 234 migrants on board.

In a statement Tuesday, Prime Minister Joseph Muscat said Malta aims "to prevent escalation into humanitarian crisis" by sharing the responsibility with other fellow EU nations. No details were given, and the statement did not say whether Malta would allow the vessel to dock.

The statement also said that Malta planned to investigate the captain of the Lifeline, run by a German non-governmental agency, nothing that he had ignored instructions.

The ship has been stranded for days since Italy's populist interior minister refused to allow it access to ports, echoing the case of the Aquarius that was refused entry to Italy and Malta, only to be taken in by Spain, 1500 kilometers (900 miles) away.

Fearful of a domino effect if Germany closes its borders, Austria has conducted a high-profile training exercise to show how it could deal with an influx of migrants along its frontier with Slovenia.

Hundreds of police and soldiers staged a dry run Tuesday near Spielfeld, 175 kilometers (110 miles) south of Vienna. The town was a major crossing point for migrants in the summer and fall of 2015.

Thousands of migrants poured through Europe's open borders daily three years ago, triggering a humanitarian and political crisis that has left deep divisions on the continent.

German Chancellor Angela Merkel is under pressure from conservative allies in Bavaria to turn migrants back at the border, a move that could prompt others to do the same.

Hardly any migrants have been arriving in Spielfeld recently.
