Residents angry over alleged religious insults beat up a Briton working at an energy company camp in southern Iraq, days after another firm suspended operations over secular unrest, officials said Tuesday.
The incidents come as Baghdad relies on foreign oil firms from the United States, Britain, China and elsewhere to help it ramp up crude output dramatically in the coming years in order to fund much-needed reconstruction.
Prime Minister Nuri al-Maliki waded into the disputes, which involved American oilfield services companies Schlumberger and Baker Hughes, calling for the deportation of the Briton, whose identity was not disclosed.
Officials said a British employee of security firm G4S working at a Schlumberger camp near the giant Rumaila oilfield had removed on Monday flags and pamphlets commemorating Imam Hussein, a venerated figure in Shiite Islam, just days before annual rituals commemorating his death.
"A British employee took down a flag for Hussein and a picture of Imam Ali (another key Shiite figure) from the cars of the security company, and tore them down with a knife," said Ali Shaddad, a member of the provincial council of Basra, which is predominantly Shiite Muslim.
Rumaila, located in south Iraq, is the country's biggest oilfield, where Britain's BP and China's CNPC have been working with oilfield services companies to ramp up output.
"This provoked a group of workers, and they went and hit him repeatedly," said Shaddad.
Videos posted on YouTube, which could not be independently verified, showed a foreigner wearing a flak jacket being dragged from a vehicle and hit repeatedly by an angry crowd of Iraqis, some of whom were wielding sticks and spades.
They showed the man eventually being pulled away by Iraqi soldiers.
Shaddad said the man was taken to a hospital in Basra and had yet to be discharged. The provincial councillor added that there were demands for Schlumberger's offices in Basra to be closed and its foreign staff deported.

Maliki himself issued a statement calling for the Briton to be deported, while also urging local residents to exercise restraint.
The British embassy in Baghdad said only that it was "aware of a consular issue, and we are following up."
The incident follows a similar one days earlier in which an Egyptian employee of Baker Hughes, another American oil services firm, also tried to remove flags commemorating Imam Hussein and Imam Ali from vehicles he was to use.
It sparked protests that spurred authorities to arrest the Egyptian, Shaddad said, on charges of insults against religion. The case is ongoing.
Baker Hughes, which said no injuries were suffered and its facility was secured, suspended its Iraqi operations in the aftermath of the incident and declared a force majeure to its clients because of a "significant disruption of business."
"While we investigate this incident, and until the work environment has stabilised, we are halting activities in Iraq," chief executive Martin Craighead said in a statement.
"We hope to resolve this issue in a timely manner, and resume operations in support of our customers and the country of Iraq, as soon as it is safe to do so."
The incidents come amid commemorations marking the death of Imam Hussein in 680 AD at the hands of the armies of the caliph Yazid. Over time, this has come to mark the symbolic split between Islam's Sunni and Shiite sects.
To commemorate the occasion, millions of Shiites converge on the city of Karbala, which houses a shrine to Imam Hussein.
Several major international energy firms operate in southern Iraq, which is rich in oil reserves. They take security precautions in the form of fortified camps and secured convoys due to the high level of violence in the country.
In a sign of the importance attached to Iraq, outgoing Shell chief executive Peter Voser met Maliki on Tuesday on a visit to Baghdad.
