Bahrain and Kuwait said on Sunday that Iran targeted their nations with drone and missile fire overnight after new US airstrikes hit Iran.
The new crossfire further strains the initial deal that Iran and the United States struck in an effort to find a permanent end to the war.
Both Bahrain and Kuwait denounced the Iranian attacks.
Bahrain's Foreign Ministry issued a statement denouncing what it called "a dangerous escalation that reveals that what Tehran is doing is not a passing act, nor an isolated incident, but rather a deliberate approach and a systematic pattern of repeated aggression against the sovereignty of the kingdom, and the security of its citizens and residents.”
Kuwait's foreign ministry denounced on Sunday a new Iranian attack on its territory.
The ministry said in a statement that it "expresses its condemnation and denunciation of... in the strongest terms, the recurrence of Iran's heinous aggression against the State of Kuwait, the latest of which was at dawn today, in a flagrant violation of its sovereignty".
The US military’s Central Command said it struck Iranian military "surveillance infrastructure, communication systems, air defence sites, drone storage facilities and minelayer capabilities” following an attack on a ship at sea early Saturday morning. That ship, the Panamanian-flagged tanker Kiku, was carrying crude oil.
