CAIRO -- The local affiliate of the Islamic State of Iraq and Syria (ISIS) has claimed responsibility for that left at least nine people dead.
The claim, which was carried by the group's Aamaq news agency, said Friday's attack was carried out by a "security detail" and that one of its men was "martyred" in it.
A gunman on a motorcycle opened fire outside the church and at a nearby store, sparking a shootout that killed at least nine people, including eight Coptic Christians, in the latest attack targeting the country's embattled Christian minority.
The gunman was also killed, along with at least one police officer, officials said.
The attack came amid tightened security around churches and Christian facilities ahead of the Coptic Orthodox Christian celebrations of Christmas on Jan. 7. Police have been stationed outside churches and in nearby streets across Cairo. Egypt's President Abdel-Fattah el-Sissi has personally chaired meetings with his top security chiefs in recent days to discuss security during New Year's Eve and the Orthodox Christmas.
In a call with El-Sissi, President Trump offer condolences Friday to the people of Egypt. He condemned the attack "and reiterated that the United States will continue to stand with Egypt in the face of terrorism," the White House said in a statement.
"President Trump emphasized his commitment to strengthening efforts to defeat terrorism and extremism in all their forms.," the statement said.
