The situation on the ground is bad. The whole world is deaf and is not watching, we need ammunition", said a rebel commander.<br/> <br />Syria's divided rebels have agreed to set up a joint leadership to oversee their battle to overthrow President Bashar al-Assad, two insurgent sources said on Tuesday as fighting raged in cities across the country.<br/> <br />Rebels hope the decision, taken after increasing pressure from foreign supporters on them to unite, will help convince those backers that they are a credible and co-ordinated fighting force deserving to be supplied with more powerful weapons.
