In a new interview with "Rising," a foreign policy analyst with the American Enterprise Institute warned that the humanitarian crisis in Yemen is getting worse.

Yemen has been rocked by a civil war since 2015 as opposing factions supported by Saudi Arabia and Iran have been fighting for control of the Persian Gulf nation.

Despite promises from Saudis that its "Decisive Storm" campaign would end early, the situation in Yemen has escalated.

"The people of Yemen are suffering and it's to the point now where we're looking at a cholera epidemic and massive risk of famine," Katherine Zimmerman said during a Wednesday interview with "Rising" co-host Buck Sexton.

Zimmerman also discussed a proposal from Saudi Arabia and the United Arab Emirates to close down the Yemeni port city of Hodeidah and how it could make the starvation problem much worse.
