The Greek Coast Guard said it is investigating the incident regarding the act of sabotage against the migrants.
ISTANBUL -- Just off the Turkish coast Tuesday morning, 40 Syrians were crammed on a rubber dinghy, desperate to reach Europe.
On board was Tanya Ibrahim, a high school art teacher from Aleppo, her 3-year-old son, Mohammed Jan, and her husband Abdeqaden, who filmed their dangerous journey. CBS News correspondent Holly Williams and her team first met them in Turkey before they set out.
They fled Syria two years ago, after their home was bombed, but they told Williams there was no regular work for Syrians in Turkey, so they borrowed $2,000 to pay a smuggler.
"We can't live in Syria, and we can't live here," Tanya told CBS News. "For the sake of our son we need to leave."
The family gave Williams and her team permission to follow them as they tried to reach Greece. They had good luck to start, with fairly calm waters, though their boat was overcrowded.
About five miles from the Greek coastline, however, an unmarked speedboat arrived from Greek waters. Abdeqaden said five men dressed in black pointed guns at them. He quickly hid his camera.
Then the men disabled the motor -- cutting the fuel supply, according to those aboard -- leaving terrified men, women and children adrift in the open sea. CBS News saw the men do the same thing to five other boats.
It's unclear if the men were affiliated with Greece's Hellenic Coast Guard. When CBS News contacted the coast guard, they didn't admit that their men were responsible, but wouldn't deny it either.
In a statement sent to CBS News, a spokesman acknowledged it was the Greek coast guard that initially located the crammed boats, but suggested the Turkish coast guard was notified and took over the incident. The Greek coast guard would not confirm or deny any specific interaction between its personnel and the migrants in the boats, saying in the statement that officials could not "be more specific at this time."
The Hellenic Coast Guard said it routinely investigated reports of such incidents, but was waiting to see the full details in CBS News' report to evaluate the information available, and would "investigate, if there's a basis for investigation."
The statement from the coast guard called the act of disabling a migrant boat and leaving it adrift at sea "categorically reprehensible," and said it was not "consistent with the mission of the Hellenic Coast Guard, or the morality, the professionalism and the humanity of its members."
CBS News has been told of several similar incidents, however, in which the Greek coast guard allegedly sabotaged refugees' boats to prevent them from reaching Europe, endangering refugees' lives in doing so.
Eventually, the Turkish Coast Guard came to the rescue and, with help from the boat carrying the CBS News team, towed the migrants to safety. Tanya and her family didn't make it to Greece Tuesday, but they're still alive, and they told Williams they'll try again -- as many times as it takes -- to reach Europe.
