The Greek coast guard is being accused of causing the deaths of dozens of migrants in the Mediterranean over a three-year period, according to a scathing report by the BBC. The deaths include nine who were deliberately thrown into the water, eyewitnesses said. Those nine were among 40 people the report alleges to have died as a result of being forced out of Greek territorial waters, or taken back out to sea after reaching Greek islands, the BBC report said. The investigation said boats are sometimes pushed back towards Turkey by the Greek government, which is illegal under international law. The Greek coast guard said it strongly rejects all accusations of illegal activities.
