BRUSSELS (AP) — Belgian Prime Minister Alexander De Croo announced on Friday an investigation into suspected Russian interference in June’s Europe-wide elections, saying that his country’s intelligence service has confirmed the existence of a network trying to undermine support for Ukraine.

“Belgian intelligence services have confirmed the existence of pro-Russian interference networks with activities in several European countries and also here in Belgium,” said De Croo, whose country currently holds the rotating presidency of the European Union.

De Croo said that Belgian agencies are working closely with the Czech authorities after a pro-Russian influence operation was uncovered there. He said that probe showed that members of the European Parliament were approached and offered money to promote Russian propaganda.

“According to our intelligence service, the objectives of Moscow are very clear. The objective is to help elect more pro-Russian candidates to the European Parliament and to reinforce a certain pro-Russian narrative in that institution,” he told reporters.
