The week in pictures: Usain Bolt's last 100m race, rising tensions with North Korea and the power of nature

Top images from around the world for the week of Aug. 5-11

Usain Bolt ended his stellar 100-metre career at the track and field world championships last week, falling short to American Justin Gatlin in his final individual race. In a tight finish, Bolt was punished for his slow start and Gatlin held him off at the line in 9.92 seconds. Fellow American Christian Coleman took silver, in 9.94 seconds, and Bolt took bronze at 9.95.

Gatlin may have stolen Bolt's thunder but still paid his respects to the legendary Jamaican sprinter, bowing down to Bolt on his way off the track. "I have nothing but respect for him," said Gatlin, who, at 35, is five years Bolt's senior. "Even with me being older than him, he's such an inspiration for me."

Tensions with North Korea

This picture released by North Korea's official Korean Central News Agency shows a rally in Pyongyang on Wednesday in support of the country's stance against the U.S.

Tensions between the two countries have been simmering all week, with U.S. President Donald Trump issuing a warning to North Korea on Friday that American weapons are "locked and loaded." Trump's remarks were the latest in an escalating war of words between Washington and Pyongyang. And following its latest series of missile and nuclear weapon tests, North Korea recently threatened to strike the U.S. territory of Guam.

Disputed election in Kenya

Preliminary results suggest President Uhuru Kenyatta had won 54.2 per cent of votes, ahead of Odinga's 44.9 per cent. But Odinga has claimed that the electoral commission database was hacked and the results manipulated.

The power of nature

Over 15,000 photographers entered this year's National Geographic Travel Photographer of the Year Contest, which showcases some of the best images captured over the past two years in locations around the world. 

Grand prize winner Sergio Tapiro was in the town of Comala, Mexico in December 2015 when the Colima volcano began to blow. A powerful eruption spewed out a cloud of ash and, at the same time, a massive lightning bolt illuminated the dark scene. Tapiro told National Geographic it was "one of the most exciting moments of my life."
