installation

The exact number of expected attendees on Tuesday is unclear, but reportedly could total over 800, including officers drawn from military installations as far as Europe, South Korea and the Middle East.

It became a permanent installation two years later and has trained thousands of service members, sending troops to battle in Operation Desert Storm and the wars in Iraq and Afghanistan.

The Danish Defence Ministry confirmed that drones were sighted near multiple military installations overnight, but did not specify which ones.

English flags, Korean spirits, reams of VHS tape and apocalyptic war zones all feature in works by the artists whose installations are going on show in this year's Turner Prize exhibition this weekend.

The installation was later removed after being reported to English Heritage, which said the site had been assessed and the pegs had caused "minimal damage".
