Secretary of State Mike Pompeo stated that his country is resolved to end humanitarian crisis in Yemen, where bloody conflict has been raged for nearly four years and led to the world's worst humanitarian crisis, according to the UN.
US insistence depends on guarantee not to get to a point where Hezbollah organization is on southern borders of Saudi Arabia, Pompeo told CNN on Saturday.
He argued that Saudis are of great support for Washington in facing Ayatollah Khamenei, the supreme leader of Iran. "We are working together to end aggressive acts in Yemen."
The US official acknowledged that the humanitarian crisis in Yemen, where millions are at risk of starvation, had reached "epic proportions" but said Trump administration put more than one billion dollars to stop this crisis, and Riyadh offered more funds, but Iran has provided no dollar.
Last Saturday, Pompeo vowed that the United States would continue supporting Saudi Arabia's military campaign in Yemen, as a means to counter Iran that backs Houthi group.
The US Senate on Wednesday took an initial vote to cut off the war support, with 14 members of President Donald Trump's Republican Party defying appeals from Pompeo and Defense Secretary Jim Mattis.
A final vote could come in the next week, setting the stage for a fresh battle if Trump vetoes the bill.
Defense Secretary stated that reducing US assistance to Saudis in the war would be a "mistake", and warned lawmakers that a US drawdown would lead to stronger Iran while reinvigorating both the Islamic State group and Al-Qaeda in the Arabian Peninsula.
Saudi Arabia has been leading a military coalition in Yemen since 26 March 2015, in support of forces loyal to President Hadi to retake areas controlled by Houthi (Ansarullah) Group seen as proxy for Iran in the Arab Peninsula country.
The conflict has left some 16,000 killed, hundreds of thousands injured, and 3 million displaced.
Yemen is facing the world's worst humanitarian crisis, according to the UN, with more than two thirds of the 28-million population in need for a type of humanitarian aid and immediate protection, including 8.4 million people unsure how to get next meal, and some 2 million children suffering severe shortage of nutrition.
