Turkish commando forces destroyed mock missile sites during military exercises in northern Cyprus on Wednesday.
It amounted to a message to Greek Cypriots who are planning to deploy Russian-made anti-aircraft missiles next year.
The exercises are continuing despite calls from the United States for them to be postponed.
On Monday, Greek Prime Minister Costas Simitis and his Turkish counterpart, Mesut Yilmaz, met on the sidelines of a Balkan summit and agreed to work toward solving their differences.
But today (Wednesday) in the divided Mediterranean island of Cyprus, the elite of the Turkish Cypriot special forces destroyed mock S-300 missile platform with time bombs.
Hundreds of Turkish Cypriots cheered as the bombs exploded.
Turkey ignored calls by the United States to postpone the military exercises, saying they had been planned a year ahead.
Turkish and Greek Cypriot jets confront each other in the skies during similar Cypriot Greek maneuvers last month.
Tensions have been running high on the island since the Greek Cypriot government announced it would deploy the S-300 anti-aircraft missiles.
The Greek Cypriots say the missiles, which are expected to be delivered in August, are for defensive purposes only.
The island has been divided since 1974, when Turkish troops invaded Cyprus following an Athens-backed coup that was intended to unite the island with Greece. All U-N efforts to seek a solution have failed.
A Turkish Cypriot state declared in the north is only recognized by Turkey, which maintains about 30-thousand troops on the island.
