News just breaking, details to follow:

According to initial reports, an Israeli tour bus was attacked at the Sarafovo International Airport in the Bulgarian vacation city of Bourgas.

A Bulgarian website reported that there were multiple casualties in a bomb explosion. Army Radio reported that at least three of the passengers were critically wounded.

The mayor of the Bourgas confirmed the attack. The airport of the city was closed.

Just a few days ago a Lebanese national was arrested on Cyprus on charges of planning to attack Israeli targets on behalf of Iran.

CNN has this photo, which it terms “unvetted”:

Updates: Today is the anniversary of the 1994 Iranian bombing of the Jewish Center in Buenos Aires which killed 85 people, no coincidence I’m sure (h/t @oskessel).

In January, Bulgaria disrupted a planned Hezbollah attack on Israelis.

There are at least 7 confirmed dead.  I have seen other reports that it was a youth sports team on board, but have not seen it confirmed yet.
