ERBIL, Kurdistan Region of Iraq - Kuwait's defense ministry announced Friday that two Kuwaiti border sites were attacked by two drones originating from Iraq, coming as regional states have increasingly voiced their frustrations over attacks emanating from within Iraq's borders.

The ministry said the two northern land border positions were targeted earlier in the day in what it described as an “aggressive and sinful attack” carried out by two explosive-laden drones guided by fiber-optic wires.

Material damage was sustained but no casualties were inflicted, the ministry said, adding that “the competent authorities immediately began taking the necessary measures to deal with the incident.”

In late March, Kuwait joined Saudi Arabia, the United Arab Emirates, Qatar, Bahrain, and Jordan in a joint statement condemning strikes attributed to Iran-aligned factions in Iraq against neighboring countries and infrastructure, urging Baghdad to immediately stop attacks launched from its territory.

Iraq’s foreign ministry later rejected any attacks on Gulf states and said the security of Arab countries is part of Iraq’s national security.

Tensions between Saudi Arabia and Iraq have risen over cross-border attacks launched from Iraqi territory during the recent regional conflict.

Earlier in April, Saudi Arabia’s foreign ministry summoned Iraq’s ambassador, Safia Taleb al-Suhail, and delivered a formal protest letter over attacks targeting the kingdom and other Gulf states.

Riyadh said it condemned the launches and would take all necessary measures to protect its security.
