Terrorist Attack in China

According to today's news, some 29 people were killed and over a hundred of people were injured by a terrorist attack in China. The goverment said some Uighur extremists did the mass killings. 

I've read some articles about the crackdown on ethnic minorities in China. Tibetan, Uighur and other ethnic groups are forced to leave their hometown and been taken away their freedom or killed by authorities.

Many countries including Japan have ignored this fact but I think it's time to speak out this issue to the world. At least, journalists must be protected their activities in China.
