In the past years the United States has sold to Saudi Arabia arms and munitions worth $115 billion, including deals with a combined value of $22.2 billion since the beginning of Riyadh’s bombing campaign in neighboring Yemen in 2015.
The United State has also provided Riyadh’s air force with refueling and logistical assistance in Yemen.
The Saudi Arabian bombing campaign has resulted in 3,800 Yemeni civilian deaths since 2015, the UN human rights office reported in August. The Saudi jets appeared to have shelled markets, hospitals, schools and other civilian targets, the report clarified.
In particular, some records reflect doubts by some State Department officials over the ability of Saudi Arabia to conduct military operations in Yemen without killing civilians and ruining "critical infrastructure."
As the death toll in Yemen continued to grow in 2015, confirming officials’ fears, the US State Department faced backlash from human rights groups.
Trying to calm down rights watchdog groups, the State Department convened a meeting with activists in October 2015. At the gathering, an attempt to whitewash Riyadh was made by implying that Saudi military shelled civilians “not intentionally.”
"The lack of Saudi experience is compounded by the asymmetric situation on the ground where enemy militants are not wearing uniforms and are mixed with civilian populations," the State Department staffer said to human rights activists at the meeting. "Weak intelligence likely further compounds the problem."
In the aftermath of the meeting, so called “no-strike lists” were issued that required Saudi military to avoid hitting such targets in Yemen as water and power sites, as well as roads used for humanitarian aid deliveries.
However, Saudi aircraft failed to fulfill Washington’s requirements, and hit and destroyed a bridge that was on the list.
Death tolls in Yemen have climbed to nearly 10,000 since the beginning of the armed conflict in March 2015, according to UN data. Saudi Arabia, which has carried out air raids in the neighboring country since the breakout of hostilities, claims that a number of civilian casualties was fabricated or exaggerated and resisted attempts to launch an independent investigation.
