Bangkok blasts prompt more accusations against Iran a day after Israelis targeted "Iran and Hezbollah are unrestrained terrorist elements, a danger to the stability of the region and a danger to world stability," Barak said. A statement from his office noted that Barak visited Bangkok on Sunday. Israeli authorities last month tipped off Thai police to a potential attack allegedly being planned in their capital, resulting in police detaining and questioning a suspected Hezbollah member. Inside Israel, minister for public security Yitzhak Aharonovich said he had ordered police to "raise the level of alert, with an emphasis on public places" after attempted attacks Monday on Israeli diplomats in New Delhi and Tbilisi, Georgia. Israel also blamed those attacks on Iran. Police spokesman Micky Rosenfeld said security had been increased around foreign embassies, in bus and train stations and shopping malls and at Ben-Gurion International Airport. The rare coordinated attempts on the lives of Israeli diplomatic representatives came a month after the latest assassination of an Iranian nuclear scientist and were set against an escalating war of words between Israel and Iran over a possible Israeli strike on Iranian nuclear facilities. Iran denied any involvement in either the New Delhi or the Tbilisi incidents. The Tbilisi attack was thwarted, while the New Delhi bombing left the wife of a diplomat and three other people injured. Tuesday's explosions in Thailand began with a series of blasts inside a residence in Bangkok. According to wire service and local news accounts, an Iranian man whose passport identified him as Saeid Moradi was wounded when a stash of explosives apparently detonated by accident inside his house. A bleeding Moradi left the residence, as did two other foreign men who did not appear to be hurt, wire reports said. Moradi then allegedly threw a grenade at a taxi cab that refused to stop for him, badly damaging the vehicle, and hurled another at police when they approached. The second grenade exploded before it reached the officers, blowing off Moradi's legs, according to Thai news and wire service reports . More explosives were found inside the house, the Associated Press reported, and police detained and were questioning an Iranian man who went to the international airport Tuesday night to board a flight to Malaysia. Barak, in Singapore, offered no evidence that the man in Bangkok was acting on behalf of Tehran, and no information about whom the explosives might have been targeting. But his remarks reflected Israel's increasing concern about a recent wave of international attacks, and the intensifying confrontation between Israel and Iran over the Islamic republic's nuclear program.
