Police in southwestern Pakistan say gunmen have killed six workers in the second apparent ethnic-based attack of the day.
Senior police official Hamid Shakeel says the gunmen stormed a home in Quetta, the capital of Baluchistan Province, and killed six workers who were painting it.
Three others were wounded. All the victims were from Punjab Province in Pakistan's east.
Earlier today, gunmen singled out and shot dead 10 passengers on a bus who were not ethnic Baluchis.
The bus was travelling to Quetta from the eastern city of Lahore. That attack was at Aab-e-Ghum, a town about 50 kilometers from Quetta.
Akbar Hussain Durrani, a senior official in the province's home department, said as many as 35 gunmen stopped the bus.
No group immediately claimed responsibility for the attack.
The attack will add to ethnic tensions in Baluchistan, where a nationalist movement led by armed ethnic Baluch groups has long sought greater autonomy from the central government.
