On August 14, 2015, the Cairo International Airport website was forced to briefly shut down after it was taken over by Muslim Brotherhood hackers, marking the anniversary of the 2013 dispersal of MB protests in Cairo's Raba'a Al-Adawiyya Square. The defaced website featured the above image and following message: "In revenge for the martyrs who have died by the bullets of the military gang and criminal Sisi since the coup, you will drown in the blood of those you have killed. We will follow you everywhere... The revolution continues and the land does not absorb blood."
