LONDON     -    British Airways and Lufthansa both said Saturday they were suspending flights to Cairo for unspecified reasons related to safety and security.

The British carrier said it was cancelling flights to the Egyptian capital for a week. The German airline said normal operations would resume Sunday.

Both carriers delivered two-sentence statements via email. British Airways attributed its cancellations to what it called its constant review of security arrangements at all airports, calling them “a precaution to allow for further assessment.” Lufthansa said it was suspending its flights as a precaution, mentioning “safety” but not “security” as its concern.
