New Delhi, Feb 13 (PTI) Israel today hinted at the involvement of Iran in the "terror attack" targeting an Israeli Embassy car here which exploded injuring a woman diplomat and three others. "This is a viciously planned terrorist action in the heart of New Delhi. We do not have any doubt regarding who stands behind it. It is the same regime which has been calling openly for years now for destruction of Israel," Israeli Ambassador Alon Usphiz said. Exuding confidence that Indian authorities will bring those behind the attack to book, the ambassador said both India and Israel share a lot in common in combating the menace of terrorism. "We have full confidence in capabilities of Indian authorities to bring these criminals to justice. We are very very confident in high levels of cooperation we have with authorities in India," he said. "Both the countries (India and Israel) have very intimate relations. We know this is shared threat we have to deal with together," Usphiz said. Tal Yehoshua(40), wife of Israeli Defence Attache, who is also working in the Embassy and an Indian driver of the vehicle, was among the four people injured in the blast. She is said to be critical and underwent a surgery with doctors saying she was stable. The blast occured at 3.16 pm at a busy traffic intersection on Aurangazeb Road not far away from the mission and the Prime Minister's Race Course residence after an unidentified motorcyclist stuck a magnetic device to the rear of the Toyota Innova vehicle.
