"I wish to express my affectionate closeness to the Christian community, hit while it was gathered in prayer, and to all the victims of such cruel violence.
"I entrust to the Lord those who have tragically died and I pray for the wounded and for all those who are suffering as a result of this dramatic event," he said.
