Canada has closed its embassy in the Egyptian capital because of security concerns.
There was no detailed explanation for the embassy in Cairo closing Monday, but a note on its website said consular services may be limited "due to unsettled security conditions."
Britain's embassy in Cairo remained closed Monday for a second day. British officials gave no details Sunday of a specific threat or when the facility would reopen.
The Reuters news agency cited a source saying a suspected militant recently detained by Egypt told authorities about plans to target foreign embassies.
Meanwhile, the U.S. embassy in Cairo was open on Monday.
