BANGKOK  - Thailand charged two Iranians Wednesday over an alleged bomb plot against Israeli diplomats, officials said, piling pressure on Tehran over accusations of a terror campaign against the Jewish state. Tensions between the Middle East arch-foes have risen sharply following three bomb incidents in world capitals in less than 24 hours, but Iran angrily rejected accusations that it was to blame. On Monday bombers targeted Israeli embassy staff in India and Georgia, with a female diplomat seriously wounded in New Delhi. Thai authorities said they had laid criminal charges against two Iranian suspects accused of involvement in a string of blasts in Bangkok on Tuesday.
