Iran's Islamic Revolutionary Guards Corps (IRGC) reported that its discovery and neutralization unit successfully defused three unexploded US-made MK-84 aircraft bombs in the country's western region.

The bombs were defused in Lorestan province, The Caspian Post reports, citing foreign media.

The MK-84, a 2,000-pound (900 kg) bomb, is capable of creating craters up to 11 meters (36 feet) deep upon detonation.

This came as hostilities escalated in the region after the US and Israel launched joint strikes on Iran on Feb. 28. In response, Tehran retaliated with strikes on Israel and other regional countries hosting US assets.

The war has been on hold since Washington and Tehran announced a two-week, Pakistan-mediated ceasefire on April 8, which is set to expire on Wednesday.
