More than 858 Yemeni civilians were killed, including 259 children, and 6,879 others were wounded in the 102-day conflict in Aden city, health officials said late on Friday.
Some of the deaths were caused by “diseases and epidemics that infected 6,214 people, including 256 cases that died.” Dr Khedir Lesour, head of the Public Health and Population office in Aden, said in a statement.
“The ongoing conflict in Aden forced two of the largest hospitals to be closed, in addition to a number of medical centers,” Lesour added.
Over the last three months, Aden -which is the trade and economic capital of Yemen - has been witnessing fierce confrontations between Iranian-backed Houthi militias and the Popular Resistance Committees, who are loyal to President Abd Rabbuh Mansur Hadi.
On Sunday, Saudi-led air strikes killed 30 civilians in an attack on a market in northern Yemen, the Houthi-run Saba news agency said.
UN mediators pushed for a humanitarian pause in fighting that has killed nearly 3,000 and left some of the 21 million people in need since March .
Saba also said that Houthi forces launched rockets against a number of Saudi army positions, including a military airport in the southern city of Najran, in response to what it described as Saudi aggression against Yemen.
The Saudi-led coalition launched fresh air strikes on Houthi targets in Sanaa, while clashes continued in Aden between Houthis and government forces.
The Houthis took control of the Yemeni capital last September, before expanding control over more territory in the country.
A Saudi-led coalition began an extensive air campaign targeting Houthi-held cities across Yemen on March 26 to allow president Abd Rabu Mansour Hadi and his government -who are in self imposed exile in Riyadh- to return to the capital.
