Two blasts targeting Coptic Christians in Egypt on Palm Sundayhave killed at least 45 people, officials say.
In Alexandria, an explosion outside St Mark's Coptic church killed 16 people. Pope Tawadros II, head of the Coptic Church, had been attending Mass inside and was unhurt, state media reported.
An earlier blast at St George's Coptic church in Tanta killed 29 people.
So-called Islamic State (IS) says it is behind the explosions. The group has recently targeted Copts in Egypt.
Following the attacks, President Abdul Fattah al-Sisi ordered military deployments to protect "vital and important infrastructure" across the country, the government said in a statement.
