Health officials confirmed the death of three women in Taiz province.

The Saudi-led coalition fights in support of the exiled government of President Hadi against dominant Houthi rebels, who are backed by forces loyal to former President Ali Abdullah Saleh.
The escalating aerial bombing comes just three days after a bombing on a hospital run by Doctors Without Borders and killed at least 20 patients in the northern province of Hajja.
The coalition escalated its bombing campaign since UN-sponsored peace talks between Yemeni rival parties in Kuwait collapsed more than a week ago.
The impoverished Arab country has been gripped by a civil war since Houthis and Saleh's forces seized power and drove the government of Hadi into exile in late 2014.
Saudi Arabia and its allies intervened on March 28, 2015. Allied air strikes and fighting on the ground in Yemen have since killed over 6,400 persons, mostly civilians.
