Bombers targeted staff at Israeli embassies in India and Georgia Monday, wounding four people.
Israeli Prime Minister Benjamin Netanyahu blamed the attacks on Iran, and its Lebansese proxy, Hezbollah, a Star Tribune article said.
"Iran is behind these attacks and it is the largest terror exporter in the world," he said in a BBC article.
Netanyahu said this is the second attempt of terrorism against innocent victims and blamed Iran for prevented plots to attack Israeli targets in Thailand and Azerbaijan.
In Dehli, witnesses said a motorcyclist placed a device on an embassy car before it exploded, a BBC article said. A bomb in Tbilisi, Geogria was defused.
Iran's news agency Irna quoted the country's ambassador Mehdi Nabizadeh in India denying any involvement, saying "any terrorist attack is condemned and we strongly reject the untrue comments by an Israeli official."
"These accusations are untrue and sheer lies, like previous times," he said.
The Tribune article said the attacks Monday may elevate already high tensions between Iran, who is accused of developing a nuclear weapons program, and Israel, who fears such a program would be a threat to the Jewish state.
Israeli officials comments have raised concern Israel may be preparing a strike on Iranian nuclear facilities.
