NEW DELHI //Two Indian investigators have travelled to Tehran to question Iranians they believe were involved in a bomb attack that wounded an Israeli diplomat's wife in New Delhi in February.
The investigators left for the Iranian capital last week after authorities there agreed to an Indian request to pursue the case, a police officer said yesterday.
New Delhi police have issued arrest warrants for three Iranians they believe planned or carried out the attack.
They suspect the three conducted reconnaissance at the Israeli Embassy in May last year before returning to New Delhi this year to plan the attack.
Police said two of the men left India before the attack but had been in contact with an Indian journalist accused of conspiring in the plot. The third left India after the attack.
They said one of the men, Housan Afshar, had also been in contact with Masoud Sedaghatzadeh, an Iranian accused of involvement in a blast in Bangkok a day after the New Delhi attack.
Mr Sedaghatzadeh was later arrested in Malaysia.
Syed Mohammad Kazmi, 50, a freelance Indian journalist who reportedly worked for some Iranian news organisations, is the only person arrested so far in the five-month investigation into the New Delhi blast.
Mr Kazmi faces charges relating to terrorist activities, attempted murder and other crimes. If convicted, he could be sentenced to life in prison.
He has denied all the charges against him.
The Indian investigators are expected to return from Iran this week, the police source said.
Meanwhile, the Indian Express newspaper reported that Indian investigators were also likely to visit the former Soviet republic of Georgia, where a bomb was discovered attached to an Israeli diplomat's car on the same day as the New Delhi attack.
The next day, three Iranians accidentally blew up their house in the Thai capital.
Israeli authorities say the similarity between the explosives linked Iran to all three incidents.
Iran has denied any involvement.
