Saudi Arabia conducted airstrikes against Shiite militias with ties to Iran. 

According to Reuters, the Saudi attacks on Kataib Hezbollah occurred around April 7. Kuwait also launched rockets at Shiite militants in Iraq on at least two occasions. Iran responded to the strikes on its Iraqi allies with attacks on Gulf Arab states.  

The US and Israeli surprise attack on Iran ignited conflict across the Middle East. The fighting between Israel and Hezbollah in Lebanon intensified, Ansar Allah in Yemen fired multiple missiles at Israel, the US pushed the Iraqi Kurds to assist the US war inside Iran, and Iran attacked every Gulf Arab state. 

The UAE and Saudi Arabia have also conducted attacks inside Iran. 

A separate Reuters report published on Tuesday explained that Saudi Arabia also conducted strikes directly against Iran. Kuwait additionally claimed that it had repelled an Iranian attempt to invade one of its islands earlier this month. 

The Iranian Foreign Minister denied the charge and claimed Kuwait captured four of its citizens who were on a fishing vessel. 

The Reuters reports come as President Donald Trump is considering breaking the ceasefire with Iran. Tehran has warned that if the US or Israel breaks the truce, it will escalate the conflict with attacks on infrastructure in Gulf states.
