Jewish groups around the world have offered condolences to the friends and family of the six Israeli tourists killed in an explosion on a bus in Bulgaria and highlighted that the blast coincided with the 18th anniversary of the bombing of the Jewish Community Centre in Buenos Aires.
Israel has blamed Iran for masterminding Wednesday's attack in the Black Sea resort town of Burgas. Investigators have also linked the 1994 attack in Argentina, in which 85 people died, to Iran but despite the Iranian government and terrorist organisation Hizbollah being charged over the attack in 2006, no-one has ever been convicted.
"While separated by years and by miles, these attacks are related: the targets were Jews, they were civilians, they were children, women and men said the president of the World Union for Progressive Judaism. "We stand with Israel and Jews around the world to decry this horror and we stand in solidarity with all who seek the paths to peace."
"Once again, Israelis abroad have been targeted by terrorists," said Abraham Foxman, national director of the Anti-Defamation League. "The attack in Bulgaria serves as another reminder that terrorism against Israelis has no borders, and that terrorists will not miss an opportunity to seek out and kill Israeli or Jewish civilians in cold blood.
"Our thoughts and prayers are with the victims and their families."
World Jewish Congress President Ronald Lauder added: "Netanyahu's comments regarding the Iranian regime's involvement in this deadly attack reminds the world of the role Iran, and the terrorist groups it supports, play in global terrorism."
"Tragically, there isn't a day that Israelis do not have to grapple with the scourge of terrorism that emanate from multiple sources including Iran, Hamas, Hizbollah and al-Qaeda affiliates," said Rabbi Marvin Hier and Abraham Cooper of the human rights organisation, the Simon Wiesenthal Centre.
"This deadly attack must serve as a warning that the international community must never isolate Israel when it comes to the battle against global terrorism."
