Sofia - Bulgarian farmers blocked border crossings and roads in the north and south of the country Wednesday, demanding higher prices for agricultural products, local media reported.

At Russe, the only bridge across the Danube along Bulgaria's border with Romania, was also blocked. The barricades were being briefly lifted once in every two hours to allow some of the waiting trucks passage to Romania.

To the east, at Vidin, police removed a human chain formed by protestors to end the blockade of a ferry across Danube and a roadblock was lifted on a road leading to Romania at Oryachovo, between Russe and Vidin.

Athens/Nicosia - Rival leaders seeking a solution to reunify the divided Mediterranean island of Cyprus focused talks Wednesday on the complex legal issue of settlement and property disputes, where thousands of individuals stake a claim on property seized decades ago.

Emerging after nearly four hours of talks, Special Representative of the UN Secretary General Taye-Brook Zerihoun told reporters that Greek Cypriot President Dimitris Christofias and Turkish Cypriot leader Mehmet Ali Tatat continued talks on property and are to meet again on February 12.

Despite the enthusiasm that greeted a new round of peace talks in September following a four-year stalemate, weekly talks between Christofias and Talat failed to produce a breakthrough in 2008.

Athens - Angry Greek farmers who have been blocking the northern border with Bulgaria demanding compensation for low prices were scheduled to decide later Wednesday on the future of their protest.

Trucks and vehicles headed for Bulgaria are re-routing to the Exohi border crossing at Drama, 30 kilometres away.

Hundreds more had joined them after arriving on passenger ferries early Tuesday to protest low commodity prices and demand fresh subsidies.
