Pope says murdered nuns in Yemen 'gave blood for the church'

Pope Francis says the four nuns killed in an attack on a home for the elderly in Yemen are modern-day martyrs and victims of global indifference.

Francis told the faithful on Sunday that the nuns "gave their blood for the church" and that they were not only victims of the attackers but also of "this indifference of globalisation".

The nuns were among 16 people killed on Friday by gunmen who stormed a retirement home run by a charity established by Mother Teresa.
