BRUSSELS — Soldiers fanned out to guard possible terror targets across Belgium on Saturday. It was the first time in 30 years that authorities used troops to reinforce police in Belgium’s cities, and came a day after anti-terror raids netted dozens of suspects across Western Europe.

In an interview broadcast Saturday, Belgian Defense Minister Steven Vandeput said soldiers could be deployed to protect certain embassies and some buildings within Antwerp’s Jewish quarter. Belgium has increased its terror warning to 3, the second-highest, following the anti-terror raids Thursday which left two suspects dead.

In France, an official disclosed that Said Kouachi, one of the gunman who attacked the offices of the satirical magazine Charlie Hebdo, had been buried.

The mayor of Reims, Arnaud Robinet, said the government insisted he allow the elder Kouachi brother to be buried in Reims because French law says residents of a town have the right to be buried there.

“He was buried last night, in the most discrete, anonymous way possible,” Robinet said in an interview on French television.

Kouachi and his brother Cherif were killed by French counter-terrorism police Jan. 9 after they killed 12 people at the offices of Charlie Hebdo. Cherif Kouachi is to be buried in Gennevilliers, a suburb of Paris where he lived, the city said in a statement.

A third terrorist, Amedy Coulibaly, killed five people including four hostages at a market in Paris before he was killed by police.
