Pope Francis has welcomed several thousand refugees in St Peter’s Square at the Vatican as the Catholic Church marked a day dedicated to them.
He said the refugees carried within themselves “a history, a culture, precious values” and urged them not to give up hope.
The refugees – including many asylum seekers – waved their nations’ flags during the address.
Pope Francis has repeatedly called on European states to welcome people fleeing war and poverty.
Later the pontiff became only the third pope to visit Rome’s main synagogue.
Hundreds of armed police and security personnel were deployed for the occasion.
Rome’s chief rabbi, Ricardo Di Segri, has said the visit is considered as a sign of 50 years of improving Jewish-Catholic relations.
In December, the Vatican said that the Roman Catholic Church did not support efforts to convert Jews to Christianity.
