Police on Wednesday held a mock exercise at Saint Andrew's Presbyterian Church in Lahore.

The exercise was carried out by Qilla Gujjar Singh Police at the Lahore church as part of a security beef up plan of churches and cathedrals countrywide after Quetta church suicide bombing.

On Sunday, at least nine people were killed and more than 50 wounded when two suicide bombers attacked a church in Quetta during the service, just over a week before Christmas.
