Iran jeopardising world peace: Israel PM

Asking the international community to draw a "red line" against Iran's support to acts of terrorism, Israeli Prime Minister Benjamin Netanyahu on Wednesday accused Tehran of jeopardising world peace.

"Iran is the biggest exporter of terror in the world. Iran's terror operations are now exposed for all to see," Netanyahu said during a Knesset (Israeli parliament) session, a day after a botched terror attack in Thailand, which Israel believes was meant to target its ambassador in Bangkok.

"Iran is undermining the world's stability and harms innocent diplomats. World countries must condemn Iran's terror acts and draw a red line. This aggression, if not stopped, will eventually spread," the Israeli Premier warned.

Four Thai nationals were wounded in Bangkok in a series of blasts that began on Tuesday when a cache of explosives ignited at a house, apparently by mistake.

One explosion blew off the leg of an Iranian who had fled, carrying what looked like grenades.

Israel also blamed Iran and Hezbollah, a Lebanese Shia faction supported by Tehran, for the bombing of an Israeli diplomatic car in New Delhi that wounded four people, including a diplomat's wife, on Monday.

A similar bomb targeting Israeli diplomats in Georgia was found under a car but neutralised on time.

Tensions between Tel Aviv and Tehran have risen sharply after three bomb incidents in world capitals.

An Israeli woman diplomat was injured in Tuesday's attack in New Delhi but a similar attack in Tbilisi was averted when the explosive device was discovered.

Blasts had ripped through Thailand's capital Bangkok on Tuesday in which one person was injured -- one of the would-be bombers, an Iranian national who had his legs blown off in the blast.
