In his Easter message, Pope Francis urged an end to "absurd violence" in conflict areas around the world while praising the breakthrough reached recently on curbing Iran's nuclear development program.
During his sermon the Pope welcomed the framework accord reached on April 2 between Iran and major world powers saying it would be a "definitive step toward a more secure and fraternal world."
The pontiff called for prayers for those killed at Garissa University College in Kenya, where Al-Shabaab gunmen massacred nearly 150 people, singling out Christians, in particular, for execution.
"May constant prayer rise up from all people of goodwill for those who lost their lives," Pope Francis said.
The Pope remembered the 21 Egyptian Coptic Christians killed by Islamic State militants in Libya and called for an end to "the present absurd bloodshed and all barbarous acts of violence."
Francis also expressed his "desire for peace, for the good of the entire people" in Yemen and Ukraine.
