A man in his 40s has been rescued from a house fire in Londonderry.
It happened just after 0500 GMT at Kavanagh Court in the Ballymagroarty area. The fire is being treated as suspicious.
The man was alone in the house in an upstairs bedroom when the fire broke out. He was taken to hospital suffering from the effects of breathing in smoke.
Police said it was thought flammable liquid had been poured through the letterbox and set alight.
They have appealed for witnesses.
Firefighter Kevin Lynch said the man was trapped in a back bedroom while the ground floor of the house was on fire.
"Our colleagues in the control room were able to keep talking to him and keep him calm - while they were talking to him, they were also in contact with the fire crews," he said.
"It meant the crews were able to go straight to the back of the house and take him out the window."
