Germany, Turkey and Gaza rulers Hamas condemned two church attacks in Egypt that left dozens dead and injured in the Nile Delta city of Tanta and the country's second-biggest city Alexandria on Sunday.
Turkish presidential spokesman Ibrahim Kalin tweeted his condolences and said, "We strongly condemn the heinous terror attacks on churches in Egypt on Palm Sunday today."
Mehmet Gormez, the head of religious affairs in Turkey, "cursed" the attacks and said they are the shared problem of all humanity.
"The immunity of a place of worship, no matter the religion it belongs to, cannot be violated and the bloodthirsty killing of innocent worshippers cannot ever be forgiven," Gormez said in an official statement.
Turkey's Ministry of Foreign Affairs also published a statement denouncing the attack in the Nile Delta town of Tanta, which killed at least 27 people.
"We convey our condolences to the bereaved families and the whole people of Egypt," the statement said before a second attack hit an Alexandria church, killing at least 17 people.
Germany has condemned the bombing and called for the perpetrators to be brought to justice.
Foreign Minister Sigmar Gabriel said in a statement Sunday that "the aim of the perpetrators, to drive a wedge between people of different faiths living peacefully side-by-side, mustn't be allowed to happen."
In a statement Sunday, Gaza's Islamist rulers Hamas described the attack as "a crime."
Spokesman Fawzi Barhoum said "Hamas wishes safety, security, stability and prosperity for Egypt and its people."
Hamas took over Gaza in 2007 after ousting forces loyal to Palestinian President Mahmoud Abbas. Its relationship with neighboring Egypt had deteriorated after the ouster of Islamist President Mohamed Morsi in 2013. Hamas has been attempting to improve ties with Cairo.
