Eighteen people have been shot dead after masked gunmen burst into a church in Pakistan.
There were about 100 people at the Roman Catholic church in the town of Bahawalpur. A service was being held for Protestants.
The six men rode up on motorbikes and locked the church doors before firing their guns.
No one has so far said they carried out the attack but police suspect a banned Islamic group might have done it.
There have been religious tensions between Muslims in the area for a long time but this is the first time Christians have been attacked.
Christians make up about 1% of Pakistan's 120m population.
