The white rubber dinghy had set off yesterday from Sabrata, taking advantage of a break in the bad weather to make a bid for Italy's shores, but the 130 or so people aboard soon ran into trouble when the wind whipped up.
"It became hellish", said AFP photographer Aris Messinis, who is aboard the Astral, a vessel chartered by Spanish humanitarian NGO, Proactiva Open Arms, which patrols the area looking for boats in distress.
The Phoenix's drone managed to pin-point the dinghy eight nautical miles off the Libyan coast, some four miles inside Libyan waters and therefore in an area off-limits to foreign rescue vessels.
Several NGO boats have been shot at or boarded by armed men for having sailed too close to Libyan waters this year.

In September the Libyan coast guard arrested two Germans from the NGO Sea-Eye, accusing them of having crossed into its territory.
"We said to the Libyan coast guard that we were entering no matter what because the boat was sinking, and they finally accepted," Messinis said.
A MAOS spokesman confirmed the rescue operation took place in Libyan waters, explaining that it was a rare occurrence, it had happened at least once before, several weeks ago, and once again with the Libyan coast guard's permission.
By the light of their floodlights the rescuers managed to pull to safety 113 people including 89 men, 11 women, 11 teenagers and two younger children.
"I was on the rubber boat with my son, he was crying and holding on to me. The sea was rough and the boat was taking on water. At one point some people started to panic," his Nigerian mother told rescuers.
