Belgium raises alert status for Brussels to highest level

BRUSSELS - Belgium raised the alert status for its capital Brussels on Saturday to the highest level, warning the public to avoid crowds because of a "serious and imminent" threat, a government official said.
The threat level for the capital was raised to level four. The level for the whole country was raised to level three out of four, implying a possible or probable threat, following last week's Paris attacks.
A spokesman for the government's crisis center declined to say why the alert status had changed.
