The United Kingdom's Royal Air Force ends its involvement in Iraq.
The United Kingdom's Royal Air Force bombs Islamic State of Iraq and the Levant-controlled oil wells in eastern Syria. At least four Tornado GR4 fighter jets, operating out of RAF Akrotiri in Cyprus, were involved in raids. The Ministry of Defence said initial analysis "indicates that the strikes were successful".
More than a dozen alleged ISIS-linked, terrorist members of Rawti Shax, a European offshoot of the Iraqi Kurdish jihadist network Ansar al-Islam, are arrested in a coordinated, multi-nation sweep by police across Europe. The operation dismantled an integrated cell in Italy, the United Kingdom, Norway, Finland, Switzerland, and Germany. The group is accused of radicalizing fighters, planning attacks targeting Norwegian and British diplomats in the Middle East, and planning to establish a caliphate in Iraq's Kurdistan region.
The United Kingdom raises its terror threat level from "substantial" to "severe" in response to conflicts in Iraq and Syria.
The International Criminal Court will conduct a preliminary examination in the claims that United Kingdom forces abused Iraqi detainees between 2003 and 2008.
