In the US, a manhunt is under way in Maine for a shooter who's killed 22 and injured about 60 in a Lewiston restaurant and bowling alley.

Police say 40-year-old Robert Card is a suspect, and have posted videos and photos of him and his car.

He's described as a certified firearms instructor and a member of the US Army Reserves.

US correspondent Dan Mitchinson says police will be following the facts - and trying to anticipate his moves.

"You're trying to guess where he may be going, what he might be doing next, now that we know that he is somebody with military experience- that's almost the worst nightmare that you can ask for in a situation like this"
