A bomb planted on a bus for a women's university has killed 11 female students in the south west of Pakistan, officials say.
Police chief Mir Zubair Mahmood said the blast in Quetta, the capital of Baluchistan province, set the bus on fire. He said another 19 people were injured.
Earlier, in a different town in the same province, militants destroyed a historic house associated with the country's founder, shooting dead a guard.
The province is home to Islamic militant movements as well as an ethnic nationalist insurgency.
