An off-duty PSNI officer was shot and wounded when he was ambushed in traffic in Co Tyrone tonight.
He is the second PSNI officer to be shot in the past five days.
The victim was attacked by a lone gunman as he sat in his car close to St Patrick's Catholic church in the Circular Road area of Dungannon and shot several times.
It is understood he was hit in the arm but was able to drive to the nearby police station.
He was taken to Craigavon Area Hospital, Co Armagh where he is said to be in a serious condition.
The latest attack came hours after the "Real IRA" claimed it was involved in the attempted murder of an off-duty policeman outside his son's school in Derry last week.
Constable Jim Doherty (43), was hit by a shotgun blast when he was ambushed as he drove his car along Bishop Street shortly after dropping his son off. He suffered injuries to his face, back and arm.
A caller to the Derry Journalnewspaper, using a recognised codeword for the "Real IRA", today claimed a second gunman was also involve in the attack, but his handgun failed to go off.
Minister for Foreign Affairs Dermot Ahern has condemned those responsible for the attack. "The perpetrators of these crimes do not represent the community," he said. "They seek only to perpetuate the violence and divisions of the past. Their actions cannot be justified."
Sinn Féin Deputy First Minister Martin McGuinness said anybody with information on the two shootings should bring it to the police.
"These people have no popular support and no strategy to achieve a united Ireland," he said. "These people are attempting to plunge our society back into conflict. "I am confident that the vast majority of people here will ensure that this does not happen."
Environment Minister Arlene Foster said it was worrying and unsettling. "Given that we have had an attempt on an officer's life in Londonderry and another attempt in Dungannon there seems to be a pattern developing here," she said. "That is something I don't think we saw developing nor is it something that people want."
DUP Assemblyman William McCrea said the shooting "reinforces my view that there is an orchestrated intimidation campaign against police officers in Northern Ireland. The time has come for the police to crush these dissident groups.
"There must be no let up in the campaign against dissident republicans. There is no acceptable level of violence."
Sinn Féin was due to nominate members to the local District Policing Partnership in Dungannon's town hall tonight. The meeting has been cancelled.
