Christians of many denominations all over the world are celebrating Palm Sunday, marking the start of the Holy Week leading up to Easter Sunday.
According to Biblical tradition, Palm Sunday commemorates the day Jesus entered Jerusalem, before his crucifixion and resurrection. He was greeted by crowds who waved palm branches and placed them on the ground ahead of him.
In Jerusalem's Old City on Sunday, the faithful and clergy held a service at the Church of the Holy Sepulchre, revered by Christians as the site where Jesus' body was laid after his crucifixion, and where they believe he rose from the dead.
Later in the day, pilgrims were expected to march from the Mount of Olives to the holy city, retracing Jesus' traditional route from 2,000 years ago.
However, because of a differing calendars and calculations, most Orthodox Christians will celebrate Easter on May 5th.
