L/Cpl Brodie Gillon, 26, who volunteered for a deployment in Iraq this year, was killed in the cowardly attack on Taji camp in Iraq, which is blamed on Iranian-backed militias, UK Defense Secretary Ben Wallace said on Thursday.
The United States and Britain on Wednesday vowed to bring to account the perpetrators of a deadly attack on an Iraqi base that killed soldiers from both countries, AFP reported.
Secretary of State Mike Pompeo and Foreign Secretary Dominic Raab in a phone conversation "underscored that those responsible for the attacks must be held accountable," the State Department said.
