JERUSALEM - Israeli Prime Minister Benjamin Netanyahu on Sunday called on Egypt to "fight terrorism together" after a bombing killed 23 people in a Coptic Christian church in Cairo.
"Israel condemns the reprehensible terrorist attack at the Coptic cathedral in Cairo," a statement from the premier's office said.
"Israel shares in the grief of the families of the victims and of the Egyptian people. We must unite forces and fight terrorism together."
Sunday's was the deadliest attack on Coptic Christians in Egypt since 2011, when more than 20 were killed outside a church in the northern coastal city of Alexandria.
Media in Israel say the Jewish state and Cairo cooperate in the struggle against jihadists fighting Egyptian security forces in the Sinai Peninsula.
Israel gave its green light for the Egyptian army to use tanks, aircraft and infantry against jihadists in the Sinai, which was demilitarised under the peace treaty the two countries signed in 1979.
