Iranian state TV said Tehran had fired 15 missiles at US targets in Iraq in the early hours of Wednesday, five days after the US killed General Soleimani, a top military chief, in a drone strike in Baghdad.
Iraq said 22 missiles were fired.
Britain’s Foreign Office has condemned the Iranian strikes, which have stoked fears of a new war in the Middle East.
The bases house US-led coalition troops who are involved in the fight against ISIS and other missions.
Britain’s Ministry of Defence said there have been no British casualties and US President Donald Trump, who visited the Ain al-Asad air base in December 2018, tweeted that an assessment of casualties and damage from the strikes was underway, adding: “All is well!”
The UK has about 400 troops in Iraq, while the US has more than 5,000.
A source told Reuters that early indications were of no US casualties.
Iranian state television claimed 80 “American terrorists” had been killed and US helicopters and military equipment damaged, without providing any evidence to back up the claims.
In a televised address, its supreme leader, Ayatollah Ali Khamenei, who wept over General Soleimani’s coffin on Monday, hailed the strikes as “successful”.
Germany, Denmark, Norway and Poland said none of their troops in Iraq were killed or injured. Iraq also said there were no casualties in its forces.
Iran for days had been warning that it would retaliate over the assassination of high-ranking General Soleimani, commander of the Quds Force, a unit of the Revolutionary Guards.
America and its allies in the Middle East had been bracing for an attack, with Washington telling the world that it was not interested in war.
Before Iran launched its attacks, Mr Trump had vowed that the US may retaliate with “disproportionate” force if Iran hit any US sites or killed any Americans.
Meanwhile, the US has banned its airlines from operating in airspace over Iraq, Iran, the Gulf and the Gulf of Oman.
Other airlines have issued warnings about flying over the region, although a number of carriers were already avoiding it.
In an incident that appeared to be unrelated, a Ukrainian passenger jet crashed shortly after taking off from Tehran’s Imam Khomeini airport, killing all 176 people on board.
Three British citizens were on the doomed Boeing 737 operated by Ukraine International Airlines, according to Ukraine’s government.
The Ukrainian Embassy in Tehran said engine failure was the cause and it was not a missile attack or act of terrorism, citing preliminary information.
