Hostages freed in Pakistan
The army says up to 40 militants were killed in the raid which was launched in the early hours of Tuesday morning. Twenty children managed to escape unhurt.

Attempts to negotiate an end to the standoff failed.
An army official says the operation is nearly complete and dozens had been arrested inside the mosque.
