Thailand makes arrest amid terror warning (AP) Updated at 5:43 a.m. BANGKOK - The U.S. ambassador to Thailand warned Friday there is a "real and very credible" threat of a terrorist attack against American citizens in Bangkok. Ambassador Kristie Kenney was elaborating on an "emergency message" sent by the embassy to American citizens earlier Friday warning of a possible terrorist attack. The message said that "foreign terrorists may be currently looking to conduct attacks against tourist areas in Bangkok in the near future." It urged Americans to "keep a low profile" in public and to exercise caution in areas where Western tourists gather. The statement gave no other details, but the Reuters news agency quoted Thai Deputy Prime Minister as saying a suspected member of the Lebanese Islamic extremist group Hezbollah had been arrested in Thailand. "A Lebanese suspect from the Hezbollah group has been taken into custody by Thai officials and police are investigating further," Chalerm Yumbumrung told Reuters. "Following concern raised by the Israeli embassy about a possible attack by a group of Lebanese terrorists in Bangkok, Thai police officials had been coordinating with Israeli officials since before the new year," Reuters quoted the politician as saying. Kenney told The Associated Press the threat was "real and very credible." It was the first U.S. warning of a foreign terror attack in Bangkok in recent memory.
