Reuters pointed out that the protesters were supporters of the "ultranationalist party in Bulgaria".

"The Associated Press and Euronews" stressed that "pro-Russian nationalists are preparing for even fiercer battles, using disinformation as an effective tool to spread fear among the people."

"Far-right opponents of the adoption of the common European currency in Bulgaria have attacked the offices of the EU's official representation in the capital Sofia," wrote France-Presse.

"The mob burned effigies of EU leaders, including European Central Bank President Christine Lagarde," the agency added.

"The protest was organised by the pro-Russian Renaissance party," the US television network ABC News said, adding, "Bulgaria, which joined the EU in 2007, has been plagued by political instability over the past few years. The new government, which was formed last month, has made eurozone membership its top priority."

Commenting on the vandalism, Deutsche Welle wrote: "Many economists believe Bulgaria would attract more foreign investment if it adopted the euro and secured a credit rating upgrade. Others argue that the EU's poorest country is not yet ready to adopt the EU's single currency."

"Politico" noted that about 10 police officers suffered minor injuries and about six people were detained. | BGNES
