Sixteen people were arrested in Belgium after a series of raids Sunday across Brussels, although a fugitive wanted in connection with the Paris attacks wasn't among them, Belgian federal prosecutors said.
The raids came as heavily armed troops and police deployed across Brussels and as the city prepared to remain under maximum threat level for a third day Monday after warnings of a Paris-style attack. The country's prime minister, Charles Michel, described the threats as "serious and imminent."
"I indicated yesterday that what we are concerned about an attack similar to the one that was carried out in Paris involving several individuals and maybe targeting attacks on several sites simultaneously," Michel said.
Schools were to remain closed Monday, and public events and transportation were to be canceled.
