The National Park Service on Monday released dozens of photographs of President Donald Trump's inauguration that appear to counter Mr Trump's claim that up to 1.5 million attended the event at the Capitol and National Mall.

The photos were released in response to news media requests made through the Freedom of Information Act.

The park service also released photos from President Barack Obama's two inaugurations. The photos show the 2009 event far outstripped the number of people who attended Mr Trump's inauguration.
