A coordinated attack on an outdoor market in northwest China has left 31 people dead and dozens wounded, prompting promises of a vigorous government response. Bombs and cars were used to inflict damage on people at the market.
The Chinese government called the early morning attack in Urumqi, the capital of the Xinjiang region, a "serious violent terrorist incident of a particularly vile nature," according to The Associated Press. Previous violent attacks have been blamed on the area's Muslim Uighur minority.

Hieu Phan, 18, is a “sneakerhead” – he collects shoes that are rare and have trading value.
Phan remembers watching reruns of the Olympics with his dad when he was very young. When Michael Jordan was on the bench lacing up his sneakers in the second quarter, his shoes caught Phan's eyes. It was a special moment for him, but not as special as when he finally got his own pair of the same shoes Jordan had been wearing: Air Jordan Olympic 7.
