Bishop Teodosije holds candles during an Easter vigil mass in the monastery of Gracanica during an Easter service, Kosovo Sunday, April 16, 2017. Across the world, Orthodox Christians are celebrating Easter, commemorating the day followers believe that Jesus was resurrected more than 2,000 years ago.

Christians around the world celebrated Easter on Sunday, as Pope Francis and others expressed concern over embattled communities in the cradle of the faith following church bombings in Egypt and attacks on civilians in Syria's civil war.

At St. Peter's Basilica in the Vatican, Francis lamented the horrors generated by war and hatred, delivering an Easter Sunday message that decried the "latest vile" attack in Syria — a bombing Saturday that killed more than a hundred people.

Thousands of worshippers flocked to Jerusalem's Church of the Holy Sepulchre, built on the site where Christians believe Jesus was crucified and resurrected.

This year, the Orthodox churches celebrate Easter on the same Sunday that Roman Catholics and Protestants mark the holy festival. The Western Christian church follows the Gregorian calendar, while the Eastern Orthodox uses the older Julian calendar, so the two Easters are often weeks apart.

In Egypt, Coptic Christians marked a somber Easter a week after twin bombings by the Islamic State group killed dozens of worshippers at churches in two separate cities.
