The pope is turning 80 this Saturday.

The pope asked Assad "to ensure that international humanitarian law is fully respected with regard to the protection of the civilians and access to humanitarian aid."

In his homily for the feast, Pope Francis denounced the exclusion of so many people “from the train of life.”

"We are united in the blood of our martyrs," Pope Francis said.
