Israel is furious over an agreement between Iran and Argentina to jointly investigate a terror bombing of a Jewish centre that killed 85 people, almost two decades ago.
Israel's Deputy Foreign Minister Danny Ayalon said the agreement, which was struck on Sunday, 'is like inviting a murderer to investigate the killings he committed.'
Argentine prosecutors have formally accused six Iranians of co-ordinating - under orders from their government - the July 18, 1994, bombing that demolished the Argentine Israelite Mutual Association building in Buenos Aires.
The centre, a symbol for Argentina's Jewish community, was destroyed. Hundreds of people were wounded. The attack came two years after a bomb flattened the Israeli embassy in Buenos Aires, killing 29 people.
Argentine officials have claimed that Iran masterminded the attack and agents of the Lebanese militant Hezbollah group carried it out.
Among those accused of involvement in the community centre bombing is Iran's current defence minister, Ahmad Vahidi.
The Argentines have spent years seeking to interrogate the six with the help of Interpol but Iran's government has refused to make them available until now.
On Sunday, Argentine President Cristina Fernandez de Kirchner announced via Twitter that her country and Iran agreed to establish an independent international 'truth commission' to investigate the bombing.
The commissioners will examine the evidence and recommend how to proceed 'based on the laws and regulations of both countries,' she said. Then, commissioners and Argentine investigators will travel to Tehran to question the suspects.
The agreement was signed in Africa by Argentinian foreign minister Hector Timerman and his Iranian counterpart Ali Akbar Salehi.
Previous Argentine probes resulted 'only in failures and scandal, with a trial that ended up being a farce' after high-level officials were accused of covering up evidence and deliberately misdirecting investigators, the Argentinian president said in a series of tweets.
Israel's foreign ministry said on Tuesday it is 'deeply disappointed' and is summoning Argentina's ambassador to demand an explanation over the joint probe.
Israel's ambassador in Buenos Aires will request a meeting with Argentine's foreign minister for clarification, it added.
'Though the (Jewish community centre) attack took place on Argentinian soil and was aimed at Argentinian citizens, the findings of the ensuing investigation by Argentinian authorities has brought up a clear resemblance with the bombing of the Israeli embassy in Buenos Aires, which occurred two years earlier,' the ministry said in a statement.
