Iran's military organisation has been fingered by Indian investigators hunting the perpetrators of an attack on the country's Israeli embassy in February.

The blast, in Delhi, left the wife of Israel's defence attaché injured and happened during a spate of attacks or attempted attacks on Israeli targets abroad. Israel blamed Iran at the time and now, six months later, Delhi police officials have confirmed that they suspect members of the Iranian Revolutionary Guard were behind the attack.

In a report seen by the Times of India, police state their belief that five Revolutionary Guard members had co-ordinated the plans for the attack with an Indian journalist.

The newspaper said that details of what the Indian investigators had discovered had been shared with Iran.

Iran has also been blamed by Israel for last month's suicide bomb in Burgas, a coastal resort in Bulgaria, in which five Israelis were killed.
