Investigations have been launched into two fatal shootings in Dublin.

The first shooting in Summerhill in the inner city was being linked to the Hutch-Kinahan gangland feud, while a second death hours later in Clondalkin is not thought to be related.

The first shots were fired shortly after 9:30 last night when two men entered the Sunset House pub, in Summerhill - part of Dublin's North inner city.

One of the men is believed to have opened fire, leaving a 35-year-old man dead at the scene.

Gardaí, who are appealing for witnesses, are focusing on a potential getaway car.

They say the silver, Cork registered, Audi was recovered in nearby Drumcondra and has been seized for technical exam.

That car is linked to another silver saloon car which left Walsh Road in Drumcondra in the direction of Home Farm Road with three men inside.

Violence broke out again just before midnight in the Kilcronan area of Clondalkin.

There, another man also in his 30's - was shot dead.

Two separate investigations are underway.
