Saudi Arabia launched numerous, unpublicized strikes on Iran in retaliation for attacks carried out in the kingdom during the Middle East war, two Western officials briefed on the matter and two Iranian officials said, Reuters reported. 

The Saudi attacks, not previously reported, mark the first time that the ​kingdom is known to have directly carried out military action on Iranian soil and show it is becoming much bolder in defending itself against its main regional rival.

The attacks, launched by the Saudi Air Force, were assessed to have been carried out in late March, the two Western officials said. One said only that they were "tit-for-tat strikes in retaliation for when Saudi (Arabia) was hit."
