British Airways has cancelled all flights to Cairo, Egypt for seven days "as a precaution to allow for further assessment".
The cancellations follow the UK’s Foreign Office warning for travellers to Egypt of a "heightened risk of terrorism against aviation".
Following the news, Lufthansa, which operates flights from Cairo to Munich and Frankfurt, Germany, said it was also suspending flights, citing "an unclear security situation".
In response to BA's decision, an official source at Egypt’s Ministry of Civil Aviation said the recent decision by to suspend its flights to Cairo was not issued by the British Department for Transport nor Britain’s Foreign Office.
It is believed Egyptian authorities are currently reviewing British Airways’ decision to suspend its flights to Cairo.
In the meantime, Egypt’s Ministry of Civil Aviation said it will be increasing the capacity of EgyptAir flights to London. The authority said it is allocating a new Boeing 787 Dreamliner to launch an additional flight to London’s Heathrow Airport.
