   Pope Francis has condemned the killing of 16 people, including four Catholic nuns, at an old people's home in Yemen. 
   
   He called Friday's gun attack in Aden an "act of senseless and diabolical violence". 
   
   Reports said the attackers pretended they were visiting their mothers to gain access to the home. 
   
   No group has claimed responsibility for the attack, though Yemeni officials have blamed so-called Islamic State. 
   
   In a statement, the Vatican said two of the nuns killed were Rwandan, one was Indian and one was from Kenya. 
   
   'Pointless slaughter' 
   
   They were working as nurses at the home and had been serving breakfast to its 80 residents when the attack occurred. 
   
   All the victims were shot in the head and had been handcuffed, the Associated Press reported, citing the brother of a victim. 
   
   The nuns were from the Missionaries of Charity congregation, which runs the home and was founded in Calcutta by Mother Teresa. 
   
   Pope Francis "prays that this pointless slaughter will awaken consciences, lead to a change of heart, and inspire all parties to lay down their arms and take up the path of dialogue", Vatican Secretary of State Pietro Parolin said. 
   
   "He sends the assurance of his prayers for the dead and his spiritual closeness to their families and to all affected from this act of senseless and diabolical violence."

   Missionaries of Charity spokeswoman Sunita Kumar said members were "absolutely stunned" by the killings. 
   
   The nun in charge managed to hide and escaped unharmed. 
   
   Yemen is engulfed in a brutal civil war between Iran-backed Zaidi Shia Houthi rebels in the north and the Saudi-Arabia backed government in the south. 
   
   Islamic State and Al-Qaeda in the Arabian Peninsula (AQAP) have both taken advantage of the war to gain ground in the country. 
   
   More than 6,000 people have been killed and 2.4 million people displaced in Yemen's war, the UN says. 
   
   Forces loyal to the government and southern militias regained control of Aden in July, aided by Saudi-led coalition air strikes and troops. ||||| 2016-03-05 Vatican Radio

target: – Four Catholic nuns and 12 others were killed during an attack on a home for the elderly Friday in Yemen, in what the Vatican is condemning as an "act of senseless and diabolical violence," CNN reports. According to the AP, six gunmen got past the home's gate in the city of Aden by pretending they were visiting their mothers. Four then entered the building and went from room to room, handcuffing victims and shooting them in the head. The nuns, members of an organization founded by Mother Teresa, were acting as nurses in the home and serving breakfast when the gunmen entered, the BBC reports. One nun was able to escape death by hiding inside a fridge. Two of the killed nuns were from Rwanda, one was from India, and another was from Kenya. A Yemeni cook and Yemeni guards were among the other victims. Pope Francis was "shocked and profoundly saddened" by the violence, according to a Vatican press release. The Vatican's secretary of state says the Pope "prays that this pointless slaughter will awaken consciences, lead to a change of heart, and inspire all parties to lay down their arms and take up the path of dialogue." A spokesperson for the nuns' organization, the Missionaries of Charity, says the nuns decided to stay in Yemen longer than required in order to continue helping people. The identity of the gunmen is unclear, but Yemeni officials are blaming ISIS. Yemen is in the midst of a civil war, which is being used as cover by both ISIS and al-Qaeda. More than 6,000 civilians have been killed since the war started.
