The UN has condemned an airstrike on a detention centre in Yemen that killed at least 60 people.
The temporary facility, which is in a stronghold of the rebel Houthi movement in northern Saada province, was struck on Friday.
It marked another deadly day in the war between Saudi led coalition forces and Houthi rebels which has been going on since 2015.
A spokesman for UN Secretary General Antonio Guterres, Stephane Dujarric, said further deadly airstrikes had been reported elsewhere in Yemen with three children among those reportedly killed in the western city of Hodeidah.
“An airstrike on telecommunications facilities in Hodeidah has also significantly disrupted vital internet services across much of the country,” Mr Dujarric said in a statement.
“The Secretary-General calls for prompt, effective and transparent investigations into these incidents to ensure accountability.”

Meanwhile, the Houthi government’s health minister, Taha al Motawakel, described the airstrikes as a “war crime”.
“The coalition (Saudi-led coalition) is targeting civilians, they attacked the detention centre in Saada province that hosts civilian inmates known by the Red Cross and were visited by them, they were directly targeted by Saudi-led coalition aircrafts. Until this moment rescuers are still searching for victims,” he said.
“We are looking at a very big crime and there is an American green light to kill civilians, that’s what we can see through targeting the detention centre in Saada province and the continuous killing of civilians without chasing the convicts or the war criminals.
“We consider this a war crime against humanity. The world should take its responsibility at this critical moment in human history, we are witnessing many victims.”
Saudi officials deny conducting offensive
But the Saudi-led coalition said reports of it targeting the detention centre were untrue, the Saudi official news agency SPA reported on Saturday.
A coalition spokesman said the target in Saada was not on no-targeting lists agreed upon with the Office for the Coordination of Humanitarian Affairs, was not reported by the International Committee of the Red Cross and did not meet the standards specified by the Third Geneva Convention for Prisoners of War.
