Today, Wednesday, the Iranian embassy in Greece denied any connection between the Islamic Republic and a plan to launch attacks against Israeli targets in Athens.

It said on Twitter, "The Embassy of the Republic of Iran strongly denies the rumors spread by Zionist sources and their baseless accusations against Iran. It is clear that their fabricated scenarios aim to divert the public's attention from their internal crisis."

Greek police said on Tuesday that they had arrested two young Pakistanis of Iranian origin who were planning attacks on areas frequented by Israelis in central Athens.

The source said that the two men set their sights on a building that includes a Jewish restaurant and a prayer hall.

Police spokeswoman Constantia Demogledo told AFP that the "mastermind" of the cell was "a Pakistani who lives outside Europe".

A police source, who requested anonymity, said that this person lives in Iran.

Israel accused Tehran of being behind the scheme and said that the Mossad helped avert the attack.

"After interrogating the two suspects in Greece, the Mossad helped uncover the network's intelligence, operational methods and ties to Iran," said Prime Minister Benjamin Netanyahu's office.

He added in a statement, "As part of the investigation, it was found that the infrastructure in Greece was part of a wide Iranian network operating from Iran towards many countries."

The announcement came at a time when the under-criticized Greek Prime Minister announced the organization of elections on May 21 against the backdrop of mounting public anger over the failures of the government, which was blamed for the tragedy of a two-train collision that took place last month and killed 57 people.

The Greek intelligence agency has also faced pressure in the past months due to the wiretapping scandal that was revealed last year.
