India on Wednesday said, it has no evidence about any individual, entity, organisation and country involved in the attack which left an Israeli diplomat critically injured in New Delhi.

Official spokesperson in the Ministry of External Affairs Syed Akbaruddin refused to speculate on any involvement.

He was asked whether there was any information with the government to show Iran's involvement in the blast, as was being claimed by Israel, and if that would change the dynamics of India-Iran ties.

Meanwhile, official sources also refused to speculate the basis of the Israeli allegation that Tehran was responsible for the terror blast.

Emphasising that India's ties with Iran whether on energy front or overall trade sector were driven by its own national interest, one official said, certain objective realities in India's economic situation will always be taken into account.

He said, there are some international measures which will also have impact on the country.
