A man who scaled the UK Parliament’s historic “Big Ben” clock tower with a Palestinian flag has been arrested, police said.

The man scaled the U.K. building on March 8 and refused to come down, putting traffic in the area at a standstill and prompting negotiators to reach him via crane

Traffic around the Palace of Westminster in London came to a standstill for much of Saturday as emergency crews tried to reach a man who climbed the Big Ben tower holding a Palestinian flag.
