Employees at the Canadian consulate in Istanbul called in Turkish authorities after a package filled with an unidentified yellow powder arrived at the building Friday.
A statement from Turkey's Disaster and Emergency Management Authority said a chemical, radiology and nuclear team was dispatched to the office.
It said one employee of the Canadian consulate came into direct contact with the suspicious package while six others had indirect exposure.

Similar packages found at both German and Belgian consulates as well so this doesn't appear to be related with the other stuff going on in Canada, but of course that's just my speculation.
