U2 will release their new album later this year.

The four-piece rock band - made up of lead singer Bono, guitarist The Edge, bassist Adam Clayton and drummer Larry Mullen Jr. - are said to be planning to release their currently unnamed thirteenth studio album, this November.

It is believed the band - who are set to play at one of the iTunes Festival gigs at the Roundhouse in Camden, North London, in September - could even have their new material ready to debut at the performance.

The album is the first to be released by the group in five years and will follow-up the their 2009 work 'No Line On The Horizon'.

However, it has been a difficult time for singer-songwriter Bono, 54, who is believed to have suffered from writers block throughout the production process.

A source told The Sun newspaper: ''The U2 comeback is very much on for this year. This album has been a real struggle for them to make.

''It's taken a long time and Bono didn't find it easy.

''But they feel very confident now and are convinced the wait has been worth it.''
