SOFIA, Bulgaria — A bus carrying Israeli youth exploded Wednesday in a Bulgarian resort, killing at least four people and wounding 27, police and hospital officials said. Israeli Prime Minister Benjamin Netanyahu called it “an Iranian terror attack” and promised a tough response.
The explosion took place in the Black Sea city of Burgas, some 400 kilometers (250 miles) east of the capital, Sofia. Images shown on Israeli and Bulgarian media showed smoke billowing from the scene — a parking lot at the local airport, where the Israeli tourists had apparently just landed. Several buses and cars were on fire near the carcass of the targeted vehicle.
Bulgaria, an eastern European nation bordering Greece and Turkey, is a popular tourist destination for Israelis.
It was not yet certain what caused the blast — whether it was the result of a suicide bomber or a device remotely detonated — and no group immediately claimed responsibility.
