ROME — Four nuns from the order founded by Mother Teresa of Calcutta are reportedly among 16 killed by gunmen who attacked a church-run retirement home in Yemen, the latest attack on Christians in the increasingly lawless country.

The women religious, members of the Missionaries of Charity, were killed when four armed men attacked the convent and home for the elderly in the southern city of Aden on Friday (March 4), the Catholic news agency Fides reported. MORE
