Explosive devices and petrol bombs used against Derry police during sixth night of violence
Local authorities have issued a statement regarding attempts to murder police officers.
The PSNI reported attempts to murder police officers in Derry have continued in a sixth consecutive night of disorder.
From before 9pm on Thursday 12 July disorder broke out in the Bogside area.
Two improvised explosive devices were thrown at police officers in the prolonged and sustained attack.
Additionally, 74 petrol bombs were thrown during the attack.
Supt Gordon McCalmont said: "I am saddened, disheartened and frustrated that yet again police officers committed to keeping this local community safe have been attacked by a small number of people within it.
"It is nothing short of a miracle that officers were not injured.
"During this reckless disorder four AEP rounds were fired by my colleagues and we have arrested three males, aged 18 and 22 years old and aged approximately 50 years old.
"The 22-year-old had been arrested for attempted murder.
"While we have seen many young people involved in these attacks over the last number of nights, it is clear that this is being orchestrated by a more sinister, adult, violent dissident republican element.
"This cannot continue. This must end now.
"I am asking every community leader and every single person with influence in Derry to help us stop these attacks on police and the wider community of the city."
