Ferries between Greek islands and to the mainland will remain tied up in port as seamen walked off the job for a two-day strike to protest pension cuts being planned as part of the government's efforts to reform the economy and meet conditions of its international bailout, ABC news reported. 

Ferries stopped running from Thursday morning until Saturday morning.

Greece has been reliant on rescue loans from three successive multi-billion euro bailouts from the International Monetary Fund and other European countries that use the euro. 

In return, creditors have demanded a series of reforms and the country's handling of its finances is under strict supervision by international debt inspectors.
