Reuters HAVANA (Reuters) — Pope Francis and Russian Orthodox Patriarch Kirill embraced and kissed on Friday in a historic meeting, uniting to issue a global appeal for the protection of Christians under assault in the Middle East.

Nearly 1,000 years after the Eastern and Western branches of Christianity split apart, the meeting at an airport terminal in Cuba was the first ever between a Roman Catholic pope and a Russian Orthodox patriarch.

“In many countries of the Middle East and North Africa whole families, villages and cities of our brothers and sisters in Christ are being completely exterminated,” they said in a joint declaration in apparent reference to violence by militant groups such as Islamic State of Iraq and the Levant.

“Their churches are being barbarously ravaged and looted, their sacred objects profaned, their monuments destroyed.”

They also said large-scale humanitarian aid was required to tend to refugees fleeing Syria and Iraq, lamenting the “massive exodus of Christians.”

Cuban President Raul Castro stood to the side during the ceremony, enjoying another moment in the international limelight after receiving Francis last year and restoring diplomatic relations with the United States recently, meeting President Barack Obama in Panama in April.

Cuba is also sponsoring peace talks between the Colombian government and leftist rebels seeking to end a 50-year war. “If it continues this way, Cuba will be the capital of unity,” Francis said.

“Now what’s left is Colombia,” Castro told reporters after the pope boarded his plane for Mexico, where Francis arrived on Friday evening for a five-day visit to some of the poorest and most violent corners of the country.

The two religious leaders, guests of a Communist government, came together only a week after the encounter was announced. Such a meeting had eluded their predecessors, but Francis had issued a standing invitation to meet anytime, anywhere.

The moment came while Kirill was visiting the Caribbean island and Francis added a brief stop on his way from Rome to a long-scheduled visit to Mexico.

“Finally,” Francis said as he and Kirill entered through doors on opposite sides of a room at Havana airport. “We are brothers.”Speech
