HALIFAX - Canadian Forces bases across the country have been ordered to consider increasing security levels after shootings on Parliament Hill and at the National War Memorial in Ottawa.

Maj.-Gen. Christopher Coates says bases have been asked to take "precautions appropriate to their environments" to ensure the safety and security of personnel, equipment and buildings.

Military and civilian personnel working in the Ottawa area have also been told to remain in their buildings until further notice.

In Halifax, gates to the waterfront navy base, the air base and other bases in the city were locked as part of the heightened security effort.

Capt. Peter Ryan of Maritime Forces Atlantic says other measures can't be discussed in order to ensure the safety and security of military personnel.

But he says the security measures aren't in response to any local incidents.
