At least 130 children lose their lives every day in Yemen due to “extreme hunger and disease,” a prominent international charity group has said.

“Without urgent, unhindered access for humanitarian organizations and an increase in funding, Save the Children is warning half of these children will most likely go without treatment,” the group said in a report on Thursday.

It also warned that the situation in the war-torn country will deteriorate unless the Saudi-imposed siege is lifted immediately.

“If left untreated, approximately 20-30 percent of children with severe acute malnutrition will die each year,” it added.

It comes less than two weeks after Riyadh announced that it was shutting down Yemen’s air, sea and land borders, after Yemeni Houthi fighters targeted an international airport near Riyadh with a cruise missile in an act of retaliation against Saudi Arabia’s crimes against the country.

Saud-Arabia and its allies have been heavily bombarding Yemen since 2015 as part of a military campaign against the impoverished country to reinstall Yemen’s former president, a ally of Riyadh.

Saudi Arabia has also imposed a crippling embargo on Yemen, causing severe food and medicine shortages and a cholera epidemic in Yemen.

Cholera has so far claimed the lives of nearly 2,200 Yemeni people.
