ATHENS, Greece (AP) — Greek police detained dozens of people Thursday during a protest at the merchant marine minister’s office over the deaths of immigrants whose boat sank as it was being towed by the Coast Guard.

Twelve people, mostly children, are believed to have died last week when a small boat carrying 28 people from Turkey into Greece sank in the eastern Aegean Sea. Only two bodies, those of a woman and a child, have been recovered.
