Fighters say explosives found along borders to target opposition supply routes will be used against army.

The Syrian government has reportedly planted landmines along its borders with Lebanon and Turkey, targeting routes used by rebels and fleeing refugees.

The Free Syrian Army, the country’s main armed opposition group, has sent a team to uncover the mines after a number of its fighters were killed by them.

The group says it will use the explosive devices against government forces.
