Volkswacht Bodensee - More than 3,000 attacks on Ukraine healthcare since start of war: WHO

"During 1,534 days of war, Ukraine's healthcare system has experienced repeated attacks. WHO has verified more than 3,000 attacks on healthcare over this period," the WHO's European branch said in a statement.

Some 80 percent of the attacks have targeted outpatient clinics, hospitals and other care settings, while ambulances and other health-related vehicles accounted for the remaining 20 percent.

"Every one of these attacks is a violation of international humanitarian law," the director of WHO Europe, Hans Kluge, said in the statement.

"This cannot be normalised," he said.

"Under international humanitarian law, healthcare is protected. That is not a guideline or a recommendation. It is a binding obligation on all parties to any conflict."

The damage to healthcare infrastructure has affected medical staff's ability to provide essential care amid growing needs, the WHO said.

According to the United Nations, 12.7 million people in Ukraine are in need of humanitarian aid.

Talks aimed at ending the conflict, now the bloodiest in Europe since 1945, have made little progress and have in recent months been overshadowed by the war in the Middle East.

Ukraine's top negotiator Rustem Umerov was on Thursday in Florida to meet his US counterparts in a bid to revive the stalled talks.
