The State Department is concerned that there is a continued risk of terrorism in Southeast Asia, including in Thailand.
In January 2012, Thai police discovered a large number of explosive materials linked to suspected Hizballah operatives.
On February 14, 2012, an explosion occurred at a house on a busy street in central Bangkok.
A few minutes later a man leaving the house threw an improvised explosive device at a taxi.
The subsequent investigation attributed the incident to individuals from Iran who may have been plotting a terrorist attack against foreign interests in Thailand but whose bombs exploded prematurely.
While traveling in Thailand you should exercise caution, especially in locations where expatriates congregate, such as clubs, discos, bars, restaurants, hotels, places of worship, schools, outdoor recreation venues, tourist areas, beach resorts, and other places frequented by foreigners.
You should remain vigilant with regard to your personal security and avoid crowds and demonstrations.
The political environment in Thailand remains beset by deep political divisions.
Protesters hold political rallies frequently to voice their opinions.
Between March and May 2010, political protests throughout Thailand resulted in the deaths of at least 91 people and injuries to over 260 people, including two U.S. citizens.
For a period of several months after the protests ended in May, there were numerous explosive attacks, including several isolated grenade and arson attacks in and around Bangkok and, on occasion, Chiang Mai.
Some of the explosive devices were discovered in public places in Bangkok, including near a major shopping center, a school, a bus stop, and government buildings.
These incidents appear to have been motivated by domestic politics and to have no apparent link to international terrorism.
The Department of State advises all U.S. citizens residing in or traveling to Thailand to monitor events closely, avoid any large public gatherings, and exercise discretion when traveling within the country.
Political demonstrations are frequent in Thailand.
Many are scheduled on the anniversary of political events, and others happen with little warning.
Demonstrations can attract tens of thousands of participants and often cause severe traffic disruptions, especially if they include processions from one site to another.
If a demonstration is expected to pass near the U.S.
Embassy or Consulate facilities, Embassy and Consulate entrances and functions may be restricted.
Demonstrations are unpredictable and can turn violent without warning.
For this reason, we encourage you to monitor local media for information about possible demonstrations and to avoid the vicinity of demonstrations.
