Gaza Freedom Flotilla crew issues 'distress signal' after spotting drone overhead

Members of the Gaza Freedom Flotilla, a vessel named Madleen, posted a video to social media late on Tuesday, urging viewers to share their "distress signal" after they spotted a drone overhead. 

The Madleen was some 80 kilometres away from Greece in the Mediterranean, on its way to Egypt, when the drone flew above it, then either turned back, or turned off its lights, the volunteer crew said. 

Their goal upon arrival in Egypt is to walk to the Rafah crossing on foot, in a bid to highlight Israel's siege on Gaza. Israel, however, has fired on such vessels before, namely in 2010 when it killed Turkish citizens on board the Mavi Marmara.
