Berlin - The German foreign ministry expressed "great concern" at the violent clashes in the Thai capital Bangkok on Friday, and "urgently" advised against travel to the city.
The German embassy had scaled back its work to a bare minimum but remained open - unlike some other embassies - a foreign ministry spokesman said.
The ministry had warned last month about the tense situation in the Thai capital, where an anti-government protest camp has come under siege from thousands of Thai soldiers.
The latest warning did not include Bangkok airport, which remained safe for transit passengers, the ministry spokesman said.
One demonstrator was killed in Friday's clashes, in the heart of Bangkok's posh commercial district.
