An Iraqi Shiite militia commander on Thursday announced his group had fired six mortar bombs into Saudi Arabia's desert overnight Wednesday.
The Shiite militia man also said the attack was "warning message" to the kingdom to stop "interfering" in Iraqi affairs.
"The goal was to send a warning message to Saudis to tell them that their border stations and patrol are within our range of fire," Mukhtar Army militia commander Wathiq al-Batat told Reuters.
The Shiite militiamen also said that he had “been angered by Saudis and Kuwaitis who he said had insulted the daughter of the Prophet Mohammad,” Reuters added.
Six mortar shells fell in a remote area of eastern Saudi Arabia near the kingdom's borders with Iraq and Kuwait late Wednesday without causing damage.
