Help them work on conflict resolution skills (sharing, taking turns, talking it out, compromising) etc. Those things do not come naturally to people and it's something you'll have to keep working with them on at different levels as they get older. With my kids, I give it a shot or two at helping them work it out, then I separate them (and take away the thing they were fighting over if applicable) and give them seperate activities to do. Sometimes separating them for a little while will work, but if they go right back at it again, then separate them for a longer period (the rest of the morning/afternoon/day, whatever).
With my older kids, if they are still bugging each other after one separation, I find them separate activities to do in the form of chores, but yours are a little young for that.
