Iran has said Israeli accusations that it was behind the suicide bomb attack on an airport bus in Bulgaria are "unfounded."
The Iranian Embassy in Sofia issued the denial.
Eight people, including the bomber, were killed in yesterday's blast on a bus carrying Israeli tourists in Burgas Airport.
The attack drew a promise by Israeli Prime Minister Benjamin Netanyahu to "react powerfully" to what he called "Iranian terror."
