Looking at the marinetraffic web site, the PMS Burullus has simply vanished without trace. Its position was last reported, what, 48 hours ago.
In the past half hour or so a French Warship described as "9014" (no other details given) has now appeared on the same bit of Mediterranean. As yet there is only one position report so there is no track to see. It is shown as heading just north of west at 10 kts.
