Media barred from visiting Balakot: Is Pakistan trying to hide damage?

Pakistan has barred media from visiting Jaish madrasa, which India bombed in Balakot on February 26th. The Pakistani security officials have sited "security concerns" for denying access to media.

Indian govt claimed that a large number of Jaish-e-Mohammed terrorists, trainers, senior commanders were killed in the attack, but Pakistan denied the toll and said no damage was caused to any buildings and there was no loss of life.

So, if no damage was caused, then why Pakistan has barred media from visiting Balakot?
