Merkel, who played a key role in negotiating the latest ceasefire, had a private audience with the pope where the two underlined their "commitment to reaching a peaceful solution to the conflict in Ukraine", a Vatican statement said.
Francis and Merkel also discussed poverty, women's rights, health and the environment -- topics that will be on the agenda at the G7 summit Germany will host in June, the statement added.
The German chancellor arrived in Rome yesterday with a 15-member delegation and paid a surprise visit to the Sistine Chapel and the Vatican Museum, a Vatican source said.
