Sunk boat had not moved for hours, data suggests, contradicting Greek officials

Tracking data indicates two vessels stood by or circled around stationary refugee boat for several hours

Tracking data suggests an overcrowded fishing boat that sank off the Greek coast last week with the feared loss of hundreds of lives had not moved for several hours before it capsized, contradicting accounts from the Hellenic coastguard, as a Pakistani police report said it was believed as many as 800 people were onboard.

Data from the MariTrace maritime intelligence service analysed by the Guardian suggests two vessels stood by or circled around the stationary boat during a period of several hours, during which the coastguard said the boat was cruising towards Italy.
