There have been further clashes in Greece between striking truck drivers and police.
Police in full riot gear hit truckers with batons to stop them from blocking a lorry from leaving an oil refinery in the northern city of Thessaloniki.
The military has now been ordered to make deliveries.
But the leader of the lorry drivers union said the stoppage would be extended.
The move is certain to raise tensions over plans to open up the sector and bring down operating costs, a reform key to liberalising the debt-laden economy.
Road freight is one of the most closed professions in Greece, with no new licences issued for nearly 40 years. Those in circulation are sold from person to person for hundreds of thousands of euros.
The action, now entering its sixth day, has seriously disrupted deliveries of fuel and food supplies, particularly to the Greek islands in the busy summer tourist season.
