The State Department has updated its travel alerts for Thailand and Ukraine, responding to an uptick in politically-charged violence affecting both countries.

In Ukraine, demonstrations have flared up after the government opted for closer economic ties with Russia rather than with the EU. Since Thursday, over 100 individuals have died in the Kiev street riots. And anti-government rallies in Bangkok claimed their twelfth casulty—a police officer—on the February 18th.

We've been monitoring the Thai situation for months, and the new travel alert sends the same message: US citizens should avoid protest sites and any large gatherings.

In the Ukraine alert, the State Department urges American travelers to maintain a low profile and to remain indoors at night.

Recent (and ongoing) protests against government deficiencies in Venezuela have not prompted an update to the current travel warning, which restricts Americans from certain areas in Caracas.

Of the three countries, Thailand is by far the largest destination for US travelers. Statistics show that over 800,000 Americans visit the Southeast Asian country annually, compared to the 134,000 that head to Ukraine and the 50,000 to Venezuela.
