The Belgian federal public prosecutor's office said on Thursday that it had thwarted a terror cell that was aiming to target the country's politicians.
Three young adults were arrested in Antwerp after having been found using drone-mounted devices, according to a report by The Guardian.
Belgian newspapers said Prime Minister Bart de Wever, the previous mayor of Antwerp, was among the intended targets.
"There are indications that the intention was to carry out a jihadist-inspired terrorist attack targeting politicians," the prosecutor's office said in a statement.
Defense Minister Theo Francken took to social media to address the prime minister, stating that "all our support goes out to you and your family. Thank you to the security services."
Geert Wilders also potential target of terrorism
Dutch far-right leader Geert Wilders suspended all of his campaign activities on Friday after the Dutch anti-terrorism agency said that the terror group also mentioned him as a target.
Police searched a residence a few hundred meters from the prime minister's home, according to The Guardian.
Federal prosecutor Ann Fransen reported that “During a search of one suspect’s home, an improvised device, potentially explosive but not yet operational, was found, along with a bag containing metal pellets."
She added that a 3D printer was "believed to have been intended for manufacturing components useful in carrying out an attack" and was found at the home of a second suspect.
The Guardian reported that the suspects, born in 2001, 2002, and 2007, were questioned by federal police and are due to appear in court on Friday, although the third suspect was released.
