An explosion at a Cyprus military depot of weapons confiscated from Iran reportedly killed at least 12 people, including two top naval commanders. Thirty injuries were reported.
Dimitris Christofias, the president of Cyprus, said: "Today we mark a dark day in July for the Cypriot nation and its people. We are shocked by this event, not just from the damage but from the loss of human life and the injury to many of our people.
"I want to express my condolences and support to the families of the victims who lost their lives carrying out their duties dutifully. Damage can be repaired, but lives cannot return," Al Jazeera reported.
The BBC said the blast occurred at the Evangelos Florakis navy base on the southern coast of the island, most likely the result of wildfires.
Al Jazeera said among those killed were two senior commanders. The explosion also knocked out the island's biggest power plant. It knocked out transmissions from some BBC Middle East relay stations.
The BBC said the explosion was believed to have involved weapons seized in 2009 from the ship Monchegorsk carrying explosives from Iran to Syria.
Al Jazeera reports: "Costas Papacostas, the Cypriot defence minister, and Petros Tsaliklides, the commander of the Greek Cypriot National Guard, resigned from their posts."
