The US Air Force has sent a chilling message to Iran after sending warplanes armed with 'bunker busting' bombs.
The US military confirmed it has dispatched powerful 250-pound bombs on A-10 Warthogs in a bid to give pilots a better chance of deterring Iran by destroying ammunition bunkers.
Forces have been repeatedly attacked by Iran-backed fighters and, according to officials, it is the first time precision-guided weapons have been onboard the warplanes.
