WASHINGTON: The United States on Thursday urged its citizens to stay away from Bangkok after deadly grenade attacks, warning that more violence was possible in Thailand's political crisis.
"Due to escalating violence in central Bangkok, all US citizens should avoid nonessential travel to Bangkok," the State Department said, upgrading a travel alert issued two days earlier.
Grenade attacks late Thursday left three people dead and scores wounded inside the business hub of the Thai capital.
"The possibility of more such attacks cannot be ruled out," the State Department said. Several European nations have issued similar warnings.
