At 6 a.m. on July 20, 1974, Turkish troops stormed into the Republic of Cyprus in accordance with Article III of the Treaty of Guarantee of the first constitution of 1960. This mandated each of the guaranteeing parties - Greece, Turkey and Great Britain - "to take action with the sole aim of re-establishing the state of affairs" if that were ever threatened.
Turkey has criticized a joint statement issued by Greece, Cyprus and Egypt in Cairo Tuesday, saying it contains "baseless claims" against Ankara.
The three countries urged Turkey to "end its provocative actions" in the Eastern Mediterranean, including exploring for oil in Cyprus' territorial waters, which they called "a breach of international law."
Cypriot government spokesman Prodromos Prodromou has condemned Turkish activities inside Cyprus' exclusive economic zone (EEZ) describing it as an invasion of the Mediterranean island's maritime domain.
"This is certainly an invasion of Cyprus' territorial waters," Prodromou told Skai radio on Wednesday.
