The U.S. is condemning a pair of small blasts in Thailand's capital and suggesting they may be linked to Iran.
Thai authorities say an Iranian man carrying grenades blew off his own legs and wounded four civilians Tuesday after a blast shook his Bangkok house.
The explosions came a day after an Israeli diplomatic car was bombed in India. Israel blamed the attack on Iran.
State Department spokeswoman Victoria Nuland said the U.S. was awaiting the results of investigations. She offered condolences to those injured.
Nuland didn't blame Iran directly. But she noted Monday's incidents in India and Georgia, and recent "Iranian-sponsored" and "Hezbollah-linked" plots to attack Israeli and Western interests in Azerbaijan and Thailand.
She called it "reprehensible" for states to use terrorism as a foreign policy tool.
