A shocking video published by the New York Times last week shows Greek authorities abandoning 12 migrants -- among them a six-month-old infant -- on a raft in the Aegean Sea.

The video, which the New York Times received from an Austrian activist and published last week after verifying its authenticity, came short before Greek elections won by Prime Minister Kyriakos Mitsotakis on Sunday.

EU Home Affairs Commissioner Ylva Johansson called on Greece to investigate the report on Monday, tweeting that she wants the incident "fully and independently investigated."

The Greek government hasn't commented on the report, but just days before his election and the release of the video, Mitsotakis called the government's migration policies "tough but fair."

'Shoved on an inflatable dinghy without any pity'

The desperate migrants abandoned by Greece at sea came from Somalia, Ethiopia and Eritrea.

"We did not think we would survive that day. They put us on that inflatable dinghy without any pity," 27-year-old Somali mother Naima Hassan Aden told the New York Times reporters.

She and her family had arrived the previous day from Jilib, a small town under the control of Al-Shabaab's Islamic extremists.

Aden was crammed into a truck and later the dinghy with 40-year-old Suleka Abdullahi and her six children, as well as Mahdi and Miliyen, two young adults captured by Greek authorities in the Lesbos forests.

The 12 migrants were eventually rescued by Turkish authorities, and New York Times reporters found them in a detention center in Izmir, Turkey, days after their odyssey in the Aegean Sea.

Many were still wearing the same clothes they were recorded in on April 11.

The Greek government has always denied any mistreatment against asylum seekers, but the video is undeniable proof that Athens violated international law governing migration.

MSF denounces Greece's violence towards migrants

The New York Times' findings are also supported by Doctors Without Borders (MSF), which has repeatedly issued alerts outlining the violence suffered by migrants who land in Greece. The day the video was shot,103 people in need of urgent medical attention had arrived in Lesbos, according to MSF.

"Our team assisted 91 people without being able to find the other 12," the NGO said. "MSF has launched multiple warnings on the serious consequences of the direct and indirect violence against people in movement in Greece. Our patients in Lesbos have repeatedly said they were victims of traumatic rejections by frontier authorities," the NGO added.
