A man has been arrested in connection with shootings and roadside bombings in southern Iraq, a British military spokesman has said.
Stephen Wright and Samuela Vanua were Royal Artillery gunners
British and Danish troops made the arrest in al Qurna, a town about 35 miles north of Basra.
Bombmaking equipment, weapons and ammunition were seized during the raid, said Major Charlie Burbridge.
Two Royal Artillery soldiers were killed in a roadside explosion and a third was shot in the area last month.
Gunner Stephen Wright and Gunner Samuela Vanua died in a roadside bomb near Ad Dayr, north of Basra, on 4 September.
Three days later Gunner Lee Thornton died from injuries sustained in a shooting at Al-Qurna, north of Basra.
