Two men have been shot in separate gun attacks in Londonderry police said today.
Both suffered gun shot wounds to the legs in what appeared to be paramilitary-style 'punishment attacks' carried out in republican areas.
The Police Service of Northern Ireland (PSNI) said they believed the shootings were linked.
In the first attack five masked men forced their way into a house in the city's Melmore Gardens and shot a man living there three times in the legs.
Soon afterwards a man was shot three times in the left leg after four masked men entered a house in Creggan Heights and attacked him.
Detectives investigating the shootings said they believed they were linked but carried out by separate groups of gunmen.
They said they were keen to speak to anyone who was in the areas between 10pm and 11pm and saw anything suspicious.
A man is also being treated in hospital after being beaten by a gang of masked men brandishing baseball bats.
He was attacked in a house in the Cuilrath Street area of Coleraine, Co Londonderry, at around 10pm last night.
The gang singled out the man in the house and beat him. He managed to escape but the gang followed him to a neighbouring house, where they assaulted him for a second time.
He is understood to have suffered a broken leg and puncture wounds to both legs.
Detectives in Coleraine said they are working to establish a motive and are anxious to hear from anyone who noticed the attackers in the area prior to the beating or afterwards as they made off.
