ATHENS, Feb 11 (Reuters) - Most of the 15 Afghan migrants who were killed off the Greek island of Chios last week when their dinghy collided with a coast guard vessel died of head injuries, not from drowning, autopsy results seen by Reuters show.
A criminal investigation has been opened into the February 3 collision - one of Greece's deadliest migrant accidents in years - in which a coast guard vessel collided with a dinghy carrying about 39 people, causing it to capsize.
