All friends, no foes. Bosnian soldiers train at the army base of Nea Sanda, near the northern Greek city of Thessaloniki, yesterday. A joint team of 90 Bosnian soldiers, including 30 Serbs, are training as international peacekeepers for future participation in the United Nations forces. The two countries signed a military cooperation pact on Monday. Skyrianos told police he had recently been receiving threats from Papadimitriou and Eleftherios Karahalios, the man arrested with him.
