In a statement, the council urged all member states to cooperate with the Egyptian government in bringing to justice the perpetrators of the attacks, which were claimed by Islamic State.
"They expressed their deepest sympathy and condolences to the families of the victims and to the government of Egypt and they wished a speedy and full recovery to those who were injured," it said.
"The members of the Security Council reaffirmed that terrorism in all its forms and manifestations constitutes one of the most serious threats to international peace and security."
They were the deadliest attacks in recent memory on the country's Coptic Christian minority.
