He did not elaborate.
"We will also work to accelerate the delivery of military equipment to the kingdom of Saudi Arabia and the UAE to enhance their ability to defend themselves", US Defence Secretary Mark Esper said at a news briefing on Friday.
Esper and Dunford declined to discuss any potential ship movements to the region, although a number of U.S. Navy vessels are nearby.
The incident has ratcheted up instability in the world's most important oil-producing region, where tensions were already high following several attacks on Saudi oil tankers and pipelines in recent months. Khurais produced 1.2 million barrels per day before the attack.
"If they're honest, then they should not make our region the site of an arms race", he said. "So they want me to know that I am not supposed to be here", he said.
Abqaiq processes sour crude oil into sweet crude, and it is transported to transshipment points on the Persian Gulf and the Red Sea or to refineries for local production.
Aramco can store as much as 66.4mn barrels of crude at four crude terminals in the kingdom and more at worldwide ports, according to its bond prospectus.
The plant has been targeted before by militants. The facilities control the flow of more than half of Saudi Arabia's oil and represent about 5% of global production.
Jubeir urged journalists earlier that Riyadh was once expecting the outcomes of a probe, which it has invited world investigators to hitch, into the September 14 strikes which initially halved Saudi manufacturing, doubtlessly the most appealing-ever assault on oil amenities on the earth's top oil exporter.

NetBlocks Director Alp Toker said that they watched four Iranian networks falling off more than 3 hours on Friday evening.
However the U.S. president has stopped short of any immediate military strike on Iran following Tehran's suspected involvement in the attack on Saudi oil fields and industry. The council runs rebel-held areas in Yemen.
"The Kingdom condemns this egregious crime which threatens global peace and security and affirms that the primary target of this attack is in line with the previous attacks against Saudi Aramco pumping stations using Iranian weapons", he said. "At this point, a single misstep could set off a chain reaction".
"I do think if Vice President Biden behaved inappropriately, if he was protecting his son and intervened with the Ukrainian leadership in a way that was corrupt, I do think we need to get to the bottom of that", Pompeo said.
He added, "The main reason behind insecurity in the region and the main enemy of Muslims is this very regime (Israel)".
