"From here, the war appears even more absurd", said the Pope in the written statement.
Francis also announced that from his sickbed, he feels a deep solidarity with people who are sick and suffering around the world.
"I feel in my heart the 'blessing' that is hidden in fragility, for it is precisely in these moments that we learn to trust in the Lord even more."
The 88-year-old Pope has now cancelled the traditional Sunday prayer for the third weekend in a row. On Friday, he was struck by acute breathing problems and was put on a respirator. But much suggests that he is now recovering from the double-sided pneumonia, according to the Vatican.
