Dubai: Saudi security forces killed two men who opened fire on police during a raid on a farm in eastern Saudi Arabia used by militants to plot and prepare for attacks, the interior ministry said on Wednesday.

The Mokhtar Brigades, a little known Shiite militant group based in neighbouring Bahrain, identified the two men as Meqdad Al Nimr and Mohammad Al Nimr.

SPA said security forces came under fire while conducting a search in a farm outside the town of Awamiya.

“The source of gun fire was dealt with immediately and neutralised and the mission was completed successfully,” the statement said, adding that four other people with a history of involvement in “terrorist and criminal acts” had been arrested.

No policemen or innocent citizens were hurt in the raid, it said.
