The revelation raises serious concerns as the country already faces a major threat of Covid-19 outbreak in the backdrop of its health infrastructure which remains in shambles due to the years of war.

There has been approximately 113,000 suspected cases of cholera in war-torn Yemen since January, according to the World Health Organization (WHO).

A total of 56 cases were confirmed by laboratory research and 29 deaths were registered from cholera.

The WHO supported 138 centres in the fight against diarrhoea and 58 centres for thirst treatment, it said.

It pointed out that diarrhoea and thirst are among the most obvious symptoms of cholera.

Yemen has been beset by violence and chaos since 2014, when Houthi rebels overran much of the country, including the capital of Sanaa.

The crisis escalated in 2015 when a Saudi-led military coalition launched a devastating air campaign aimed at rolling back Houthi territorial gains.

Since then, tens of thousands of Yemenis, including civilians, are believed to have been killed in the conflict, while another 14 million are at risk of starvation, according to the UN.
