An Iranian man carrying explosives blew off his own legs and wounded four other people in two blasts Tuesday in Bangkok, Thai authorities said. A third blast occurred in a nearby house.

Security forces found more explosives in the assailant's rented house in the capital, but it was not known what targets they might have been meant for, Police Gen. Pansiri Prapawat said.

A day earlier, an Israeli diplomatic car was bombed in New Delhi, and Israel blamed Iran for that attack. Authorities did not immediately say if a link was suspected, but Israeli Foreign Ministry spokesman Yigal Palmor said in Jerusalem, "we can't rule out any possibility."
