Athens - Greece is detaining hundreds of illegal immigrants in cramped an squalid conditions at a reception center on the Mediterranean island of Lesvos, the French charity Medecins Sans Frontieres (MSF) charged Wednesday.

Some 800 immigrants, many of them from war-torn Afghanistan, are living in overcrowded rooms in the detention center without proper sanitation and medical care, according to the agency. Some are suffering from serious diseases.

"They do not have adequate access to showers and toilets," MSF local project leader Giorgos Karayiannis was quoted by the Greek daily Kathimerini as saying.

Athens - Greek police destroyed a bomb which was set to go off outside a policy research institute which is affiliated with the European Union, reports said Tuesday.

Gela, Sicily  - An ancient Greek ship returned to surface Monday some 2,500 years after it sank in the Mediterranean Sea and two decades after its wreck was discovered by divers off Sicily.

Ship sirens wailed and Italian culture officials and other onlookers applauded as a crane lifted from the waters what remains of the 21-metre-long wooden vessel, the ANSA news agency reported.

The ship's 11-metre-long keel and part of the stern, both of which were preserved as the vessel lay buried for 25 centuries under clay below the sea floor, are to be transported to the Sicilian port of Gela.

Nicosia - The two leaders of the ethnically divided island of Cyprus were set to meet again on Friday to decide whether the conditions were favourable to launch direct reunification talks.

Cyprus President Dimitris Christofias and Turkish Cypriot leader Mehmet Ali Talat have held several meetings to discuss progress made by working and technical groups striving to set the groundwork for the start of peace talks to end the decades-old division of the island.

The working and technical groups from both communities are trying to narrow the divide on a number of issues ranging from environmental protection, health, security, power-sharing, culture, ways of linking the island's two economies as well as property and territory disputes.
