Police in China say they’ve arrested the remaining suspects in the gruesome machete attacks on civilians at the train station in Kunming city.  It comes as a video of one of the attackers has hit the internet via a Chinese video sharing site.

It appears to show police with clubs whaling on a female in a hijab-like outfit outside the train station.  Cops say eight suspects armed with knives and swords hacked and slashed at commuters, killing at least 29 people and leaving 143 wounded.  The female suspect was captured at the scene, and four men were shot to death.

The state news agency says the remaining three suspects were captured.  They allegedly possessed flags and literature associated with the Islamist separatist movement in Xinjiang, hundreds of kilometers to the northwest from Kunming.  Some experts say this indicates a troubling shift in tactics.

“It must have taken a lot of planning and involved the recruitment of a large number of attackers who assumed most would die,” said Gardner Bovingdon, an expert on the history and politics of Xinjiang at Indiana University in the United States.

Beijing immediately labeled the incident as “terrorism”, but Washington at first referred to it as a “tragedy”, which drew angry accusations of double standards on Chinese social media.

“You can't class this attack as other than a terrorist attack,” said Michael Clarke, an expert on Xinjiang at the Griffith Asia Institute in Brisbane, adding that it was designed to “induce fear amongst the Chinese populace”.
