A major military parade that marked 70 years of communist rule in China began.
Chinese President Xi Jinping mounted a limousine opened by symmetrical ranks of troops and military vehicles, shouting "Hello comrades" as they passed.
The troops shouted back "Hello President" and turned their heads in unison to assist the President.

The parade aimed to show the country's military capabilities
Marching troops, a military band, and a military salute were deployed as President Xi addressed a crowd of thousands following a flag-raising ceremony in Tiananmen Square.
The square was open to guests only, but the president's speech was broadcast live nationwide.
The Communist Party of China organized the large parade to show the country's military capabilities and mark the anniversary of the founding of the People's Republic of China.
A new ballistic hypersonic nuclear missile – believed to be capable of breaching missile shields – was among the weapons displayed during the event.
The parade in central Beijing includes 15,000 soldiers and more than 160 aircraft.
A large part of the city's main street was closed for the event and buildings along the route were also closed.

It is a day of protest expected in Hong Kong, with posters announcing the action calling for October 1 to be marked "A Day of Mourning."
Pro-Beijing protesters fought with a small group of pro-democracy protesters in Hong Kong, although police tried to keep the two groups separate.
The pro-democracy protesters planned to march at the 70th anniversary celebrations.

Cheung, representing Hong Kong leader Carrie Lam, said the government would use new ideas to solve the problems expressed by protesters.
