New Delhi, Feb 13: An Israeli embassy car exploded in national capital New Delhi seriously wounding four, including a woman diplomat, on Monday in a terror attack emphatically blamed on Iran by Israel.

The attack occurred around 3 pm near the 7 Race Course Road residence of Prime Minister Manmohan Singh when, officials said, a biker apparently followed the car and then stuck something magnetic on the vehicle causing the explosion. The Innova SUV car was charred after it exploded near a petrol pump.

Tal Yeshova, the 42-year-old diplomat who reports said was going to take back her children from school, was seriously injured and rushed to the hospital. The driver Manoj Sharma was also injured.

Two other occupants of another car sustained minor injuries. "It was a difficult day for us," Israeli embassy spokesperson David Goldfarb told IBNS.

He said Iran was targeting Israel for the past few weeks and on Monday they succeeded in India. He, however, said Israel is confident that India would cooperate and do everything to bring the culprits to justice.

"Iran is behind the attacks on Israeli embassies, it is the largest exporter of terrorism in the world," Israeli Prime Minister Benjamin Netanyahu tweeted soon after the attack in New Delhi and the abortive attempt in Georgia.

Delhi Police Commissioner B K Gupta said the cause of explosion "may have been some kind of a magnetic device which was used to target the car."

He said a passing biker might have stuck something on the car. Eyewitnesses also said they said a biker following the car and then sticking something on it.

Forensic experts are now examining the car and the spot to ascertain the kind of explosives used. External Affairs Minister S M Krishna soon issued a statement.

Krishna said: "India very strongly condemns such incidents and it is going to be fully investigated and the culprits will be brought to justice at the earliest."

"I have just spoken to the Israeli Foreign Minister and I have reassured the Israeli Foreign Minister that the law of the land will take its course."

"The investigation has already started and we will continue with it and then keep him posted as and when we get progress report of the investigation," Krishna said. "We are awaiting further information about the well being of the victim," he said.

Earlier, Israel's Foreign Minister Avigdor Liberman was quoted as saying to The Jerusalem Post," Israel knows exactly how to identify those responsible for the attacks."

Embassies and consulates across India have been put into high alert in the wake of thew incident.
