A consulate employee speaking to a Turkish television interviewer said workers received an email telling them to leave the building immediately.

“We couldn’t grab our bags or jackets,” she said in Turkish. “They took us outside. We gathered outside the consulate, We were told an envelope came to the consulate, there was a powder inside, that it was dangerous, and that we were being sent home.”

The Belgian Consulate, asked by CNN about the security incident, said police were investigating a substance found in an envelope sent there.

The air conditioning system in the consulate has been turned off, Semple reported. “And … anyone who was exposed to the package has been kept in that room, cordoned off from everyone else as a precaution.”

The Canadian Embassy in Ankara, Turkey’s capital, is also closed, but that has been attributed to shortened Friday hours, and not any threat.

On Thursday, Canadian Forces officials said they were assessing whether heightened security was necessary at bases after a shooting on Parliament Hill on Wednesday left an Ontario reservist dead. Also mentioned were installations abroad.

“We will carry on all our missions at home and abroad in a steadfast, resolute and vigilant manner, and serve our nation and her people,” said Gen. Tom Lawson, chief of Canada’s defence staff, in a statement.
