Gunfire and explosions echoed across the death zone of this holy city.

Outside, screams, explosions, and weapons fire echoed across the sky.

A heartbeat later, a huge explosion of noise echoed through the room.

A last explosion echoed above and the ground shook in sympathy.

A double explosion echoed his, and the soldiers found themselves staring at one another over an empty clearing.

Suddenly a loud flat explosion echoed inside the confining walls of the square.

Much closer, an explosion echoed from the walls of the administration buildings.

The explosion echoed in his ears and he felt the heavy recoil.

A loud explosion echoed through the sprawling compound, and the camp went dark.
