Pope Francis has used his Easter address to condemn an attack in Syria that has left more than 100 people dead.
On Saturday buses carrying evacuees from Syrian towns near Aleppo were bombed, killing at least 112 people, including aid workers and children.
A vehicle filled with explosives targeted the buses, which were leaving government-held towns.
Delivering his annual Easter message to pilgrims gathered at the Vatican, the Pope denounced the "latest vile attack on fleeing refugees".
May [God] sustain the efforts of those who are actively working to bring comfort and relief to the civilian population in beloved Syria, who are greatly suffering from a war that does not cease to sow horror and death.
The Pope also spoke out against modern forms of slavery and discrimination.

There was a heavy security presence at his address at St Peter's Square due to recent attacks on Coptic churches in Egypt, which killed at least 45 people.
Islamic State militants claimed responsibility for the attacks.
