Seventeen U.S. service members have been killed since the war in Iran began.
President Donald Trump announced "major combat operations" against Iran on Feb. 28, with massive joint U.S.-Israeli strikes targeting military, government and infrastructure sites.
Delegations from the U.S. and Iran entered negotiations in June aimed at a war-ending deal based on a memorandum of understanding signed by both countries.
The U.S. and Iran have nonetheless continued to exchange strikes, with the strategic Strait of Hormuz the primary flashpoint.
The Kuwaiti Army issued a statement on Monday saying its air defenses "are currently confronting attacks by hostile drones," again condemning "Iranian aggression."
In Bahrain, the Interior Ministry said that its air raid sirens were sounded at least twice on Monday morning. The Bahrain Defence Force later confirmed fresh Iranian attacks on the kingdom.

United States forces conducted another wave of attacks against Iran Sunday evening, marking the ninth consecutive night of strikes, according to U.S. Central Command.
"The strikes will continue degrading Iranian military capabilities used to attack commercial vessels and civilian mariners transiting the Strait of Hormuz," CENTCOM said.
Strikes targeted "Iranian military command centers, air defense and coastal surveillance sites, maritime capabilities, missile and drone launch sites, and communications networks," in an effort to weaken Iran's ability to control the Strait of Hormuz, CENTCOM said.
A U.S. service member was killed and another wounded Saturday during what U.S. Central Command (CENTCOM) called "a controlled detonation of unexploded ordnance from a downed Iranian one-way attack drone" in northern Iraq.
The wounded service member's injury was "minor," according to CENTCOM.
Saturday's death brings to 17 the total number of U.S. service members who have been killed since the war in Iran began.
CENTCOM also released an update on the U.S. service member who was reported missing on Friday.
"After a thorough search, U.S. military personnel found unidentified remains at the location earlier today. An examination process to verify the remains is ongoing," CENTCOM said.
