Six police officers have been injured in two cross-border car-ramming attacks in south Armagh.
In the first, the PSNI was alerted by Garda officers about a white Citroen Berlingo van that had crossed the border from the Republic and made its way to Crossmaglen.
It was found in Lismore at around 3.30am on Sunday, but before the driver could be spoken to, the police vehicle was rammed along with a taxi bus before the van made off. Two officers were injured.
At 5am, police investigating the earlier incident flagged down a dark Audi A6 on the Dundalk Road. But it failed to stop, ramming two police vehicles before making a getaway. Four officers were hurt.
Police in south Armagh are appealing for information about the collisions.
Sergeant Sam Hoey said: "Following these two incidents, we now have six officers who were out working to keep the people of south Armagh safe off work with their injuries and three police vehicles off the road."
