A parcel bomb burst into flames at the Swiss embassy in the Greek capital Athens and controlled explosions were carried out on packages at the Russian and Bulgarian embassies. Greek police said a total of five parcel bombs had been discovered in the capital today, just days before local elections. The blasts follow similar packages addressed to three other embassies and President Nicolas Sarkozy yesterday. A police source said an employee at the Swiss embassy narrowly escaped injury when a suspected parcel ignited early today. Switzerland's foreign ministry said the device had been left at the entrance to the embassy in Athens, and burst into flames when it was being checked by staff. Meanwhile, controlled explosions were carried out on suspected packages at the Russian and Bulgarian embassies, and on another outside the Greek parliament.
