Alternative for Germany has surged to the best showing by a far-right party since World War II in the national election and became the strongest political force in parts of the country.

Belgium’s federal prosecutor’s office says police have searched the residence of an employee of the European Parliament and his office in the Parliament’s building in Brussels over suspected Russian interference.

German authorities say a man who works for a prominent German far-right lawmaker in the European Parliament has been arrested on suspicion of spying for China.
