A number of Egyptian cultural institutions across the country have declared three days of mourning on Sunday, after bomb attacks on two Egyptian churches killed at least 45 people and wounded scores more.
Among the culture ministry's departments that announced the complete suspension of their activities across venues are the Cultural Palaces Sector, the Theatre Sector, and the Cultural Development Fund.
Earlier on Sunday the Cairo Opera House announced it had suspended its activities in Cairo, Alexandria and Damanhour for three days.
The facilities will reopen on Wednesday.
The office of the Egyptian presidency has also announced three days of national mourning.
One of the attacks, carried out by a suicide bomber, targeted the Coptic Orthodox Cathedral in Alexandria.
The second targeted St George's Church in Tanta.
Both have been claimed by the IS militant group.
