Oasis have teased fans with a big announcement alert after posting a cryptic message on their Facebook.com page.

The group split in 2009 and bandmate brothers Noel and Liam Gallagher have been estranged ever since, taking it in turns to bash each other in the press and dismiss talk of a 2014 reunion to mark the 20th anniversary of the release of Oasis' breakthrough album Definitely Maybe.

But a month after the band made its full back catalogue available on various music streaming services, there's a big announcement brewing on Wednesday at 9am (Gmt).

A video featuring still photos of the band in their early days was posted online on Tuesday (25Feb14), alongside the caption "26 Feb 9Am". The announcement will be made at oasisinet.com.
