“I think most especially of the men and women killed at Garissa University College on Good Friday,” the leader of the world’s 1.2 billion Catholics said.
“May those who commit such brutality come to their senses and seek mercy.”
The gunmen hunted down Christians while sparing Muslims in that attack. Francis has repeatedly expressed alarm about Christians being targeted for their faith and condemned the beheading of 21 Egyptian Copts in Libya in February.
He urged the visiting bishops to work with Christian and non-Christian leaders to promote peace in predominantly-Christian Kenya.
Al Shabaab said Garissa was revenge for Kenya sending troops into Somalia to fight alongside African Union peacekeepers against the Islamist group.
