The International Committee of the Red Cross (ICRC) said 165 cases of attacks on health institutions and medical staff have been recorded in Yemen since the war began in 2015.
The agency turkish "Anatolia" quoted spokeswoman for the Red Cross in the Middle East, Sarah Zogari, as saying: "The war has greatly affected the possibility of provid Yemenis in various regions.".
"Since the start of the war in Yemen in 2015, 165 health centers, ambulances and paramedics have been damaged or attacked.", she said.
Zougri reported;: "Only 51 percent of health facilities in Yemen are still functioning."
She confirmed that "The lack of medical derivatives, sanitary ware, medicines and a shortage of medical staff has forced many health centers to close.", she said.
She points out that the number of people infected with preventable diseases such as cholera, meningitis and measles has increased in Yemen, stressing the inability of the health system to cope with the increasing incidence of these diseases.
She explained: "The conflict in Yemen has led to the deterioration of infrastructure and water systems, which has led to the resurgence of infectious diseases such as cholera, diphtheria and measles."
Yemen has been devastated by a five-year armed conflict between the government backed by the Saudi-led coalition and the Iran-backed Houthis. The conflict erupted after the Houthis ousted the government and seized power in late 2014.
More than 11.000 civilians have been killed and tens of thousands of others injured in the war. Millions have been displaced and tens of thousands have fled outside the country.
The coalition has been responsible for the vast majority of civilian casualties, according to the UN and international human rights organizations.
The conflict has caused what the United Nations calls the world's worst humanitarian crisis.
More than 24 million people, more than 80% of the country's population, are in need some form of humanitarian or protection assistance, including 8.4 million people who don't know where their next meal will come from, according to the UN.
