(NewsNation) — The Bahraini military says its air defenses intercepted several Iranian attacks Sunday before they reached their targets. However, Tehran claims to have struck a U.S. military base, Reuters reported.

Iran's Islamic Revolutionary Guard Corps said it had launched six drones targeting U.S. air defense radar at Al-Rifaa helicopter base, Iranian state-run press TV reported.

The attack was in response to "hostile U.S. actions," Iran's Fars news agency reported.

Bahraini military accused Tehran of continuing a "systematic hostile approach" toward the kingdom.

On Friday, Iran's Revolutionary Guard said it destroyed a U.S. early-warning system in Bahrain, NewsNation previously reported.
