Three arrested during protest at Shell refinery in Mayo

Gardaí say three people have been arrested during a demonstration this morning at the site of the controversial Shell refinery being built in Co Mayo.

Several hundred demonstrators are understood to have attended the blockade arranged by the Shell to Sea campaign group.

Several hundred gardaí are also at the site.

The organisation says there were some minor confrontations and scuffles, but the overall demonstration is "pretty peaceful".
