An airstrike has hit a Doctors Without Borders hospital in Yemen, killing 11 people.
At least 19 people were injured when the Saudi-led coalition airstrike hit the hospital in Abs, in Yemen's northern Hajja province.
MSF said at least 11 are dead after the strike - including one staff member.
A Reuters witness said medics could not immediately evacuate the wounded because war planes continued to fly over the area and they feared more bombings.
The facility is run by aid group Medecins Sans Frontieres.
“This is the fourth attack against an MSF facility in less than 12 months. Once again, today we witness the tragic consequences of the bombing of a hospital.
"Once again, a fully functional hospital full of patients and MSF national and international staff members, was bombed in a war that has shown no respect for medical facilities or patients.
"An aerial bomb hit the hospital compound, causing 11 people to lose their lives”, says Teresa Sancristóval, desk manager for the Emergency Unit in Yemen.
MSF said it has supported ABS hospital since July 2015 and treated 4611 patients there.
Yemen is embroiled in a deadly civil war with rival forces battling for control of the country.
A rebel group known as Houthis seized control last January, triggering a Saudi-led military intervention.
The conflict is seen as a lightning rod for regional tension between Shia-ruled Iran and the Sunni-led Saudi Arabia.
