Four Saudis who participated in the 2018 killing of the Washington Post journalist Jamal Khashoggi received paramilitary training in the United States the previous year under a contract approved by the State Department, according to documents and people familiar with the arrangement.

The instruction occurred as the secret unit responsible for Khashoggi¡¯s killing was beginning an extensive campaign of kidnapping, detention and torture of Saudi citizens ordered by Crown Prince Mohammed bin Salman, Saudi Arabia¡¯s de facto ruler, to crush dissent inside the kingdom.

The training was provided by the Arkansas-based security company Tier 1 Group, which is owned by the private equity firm Cerberus Capital Management. The company says the training - including ¡°safe marksmanship¡± and ¡°countering an attack¡± - was defensive in nature and devised to better protect Saudi leaders. One person familiar with the training said it also included work in surveillance and close-quarters battle.
