An Iran-flag aframax tanker released from detention in Greece last month is now moving into position to take its seized cargo back.

If it succeeds, the way will be open to resolve an acrimonious stand-off between Iran and Greece in which about 70 seafarers have been caught up in tit-for-tat tanker seizures over the past three months.

According to vessel trackers and sources familiar with the issue, the 115,400-dwt Lana (built 2003) was towed last weekend from its former arrest location at Karystos in the Aegean, to the Piraeus anchorage.
