Washington: The US has no information yet on who were involved in the bombing on Israeli diplomats vehicle in New Delhi and attempted attack on Israeli diplomatic personnel in Georgia, the White House has said.

"We have no information yet on who is responsible for these attacks, so we are still evaluating what happened," Jay Carney, White House Press Secretary told reporters.

White House statement came after Israel Prime Minister Benjamin Netanyahu had alleged that Iran was behind these attacks.

Iran is behind these attacks; it is the largest exporter of terrorism in the world, Netanyahu had alleged.

"I don't have an assessment to give you of what Israeli government is saying. I simply can tell you that we have not made a judgment yet, because details are still emerging regarding what happened in both New Delhi and Tbilisi," Carney said when asked about the Israeli statement.

"We have no information yet to share with you about who was behind those attacks, but we're obviously working and discussing with the Israelis and others to ascertain exactly that," he said.

"We condemn in very strong terms the attempted attacks against Israeli targets in New Delhi and Tbilisi. These incidents underscore our ongoing concern regarding the recent targeting of Israeli interests overseas," Carney said adding that the US continues to examine the situation.

"Details are still emerging regarding those incidents," he said.

Earlier in the day, US Secretary of State Hillary Clinton said the US places a high priority on the safety and security of diplomatic personnel around the world.

"We stand ready to assist with any investigation of these cowardly actions," she said.
