Greenpeace Shard climbers: Environmental activists in London attempted to climb Western Europe's tallest building Thursday, in protest of drilling for oil in the Arctic. The Greenpeace Shard climbers were about halfway up the skyscraper by midmorning.
Six environmental activists were attempting Thursday to scale the Shard, Western Europe's tallest building, to protest drilling in the Arctic by oil companies.
London's Metropolitan Police Force said officers were called to the building before dawn and were monitoring the situation.
By midmorning, the climbers were about halfway up the glass-clad skyscraper, which opened earlier this year.
Management of the Shard said the building was open, and "we're working with the relevant authorities to try to ensure the safety of all concerned."
