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 Pakistani police said on Monday they believed up to 800 people were onboard, a Guardian analysis of ship movements supplied by the MariTrace service indicated two vessels - the Lucky Sailor and the Faithful Warrior - stood by or circled round the stationary trawler for at least four hours.
