Iran’s UN envoy accused Israel on Wednesday of plotting and carrying out a suicide bomb attack on a bus in Bulgaria a week ago in which five Israeli tourists were killed.

A suicide bomber blew up the bus in a car park at Burgas airport, a popular gateway for tourists visiting Bulgaria’s Black Sea coast, killing himself, the Israeli tourists and the Bulgarian bus driver and wounding more than 30 people. …

Some analysts believe Iran is trying to avenge the assassinations of several scientists involved in its controversial nuclear program that it blames on Israel and the United States. Israeli diplomats have been targeted in several countries in recent months by bombers who the Jewish state maintained had struck on behalf of Tehran.
