Police had missiles and petrol bombs hurled at them during a security alert in the North today.
Officers came under fire from youths as young as 10 while they completed a security operation on the Newry bypass close to the border.
Police arrested one youth and have now completed their work.
Dissident republican group the Real IRA claimed responsibility for the alert. The security forces discovered an exploded device in a lane in the area on Wednesday and another spent explosive earlier this evening.
They were removed for forensic examination. A spokeswoman for the police said they had been intended to injure officers.
