New Delhi: With investigators identifying three Iranians as suspects in the terrorist attack on an Israeli diplomat here, India is seeking Iran's cooperation in bringing those involved in the dastardly attack to justice.

However, the Ministry of External Affairs (MEA) refused to draw any conclusion, saying investigations in the case are ongoing.

"On the basis of thorough and carefully undertaken investigations, three Iranians have been identified by the investigating authorities as suspects in the terrorist attack on an Israeli diplomat in New Delhi on February 13, 2012," official spokesperson in the MEA Syed Akbaruddin said.

He said warrants of arrest against these persons have been issued and the process of issue of red corner notices has been initiated but maintained that "investigations in the case are on and no conclusions can be drawn at this stage".

"We have informed the Iranian Ambassador of these developments so as to seek the cooperation of the Iranian authorities in bringing those involved in this dastardly attack to justice," he said.

Earlier, City Police Commissioner B K Gupta said the three Iranians -- Houshang Afshar Irani, Syed Ali Mahdiansadr and Mohammadreza Abolghasemi -- had done a recce of the Israeli Embassy earlier with the help of an Indian journalist Syed Mohd Ahmad Kasmi (50) who was arrested on March six.

Investigators claimed they tracked Kasmi after finding his links with one of the Iranians who was in touch with the head of the module which carried out the attack in Bangkok.
