Seventeen passengers were hurt when a Bulgarian river cruise ship lost steering and hit the sides of a lock on the Danube in Austria, the apa news agency reported Saturday. Eleven of the injured were taken to hospitals.

The ship with 142 passengers aboard, most of them from Germany, temporarily lost power to its electronics system and became unsteerable as it passed through narrow locks at 9:45 p.m. Friday, apa reported.

The ship’s power was restored but not before the bow and stern struck the concrete sides of the lock passage near the town of Aschach, a few miles upriver from Linz.

The ship sustained minor damage and continued to its next port. The cause of the loss of electrical power was under investigation.
