Another weekend of snow caused Bosnia more of the problems it hoped it had dealt with last week. Many villages are still cut off from regular transport links, electricity and water.

“Half of the territory of Albania is covered by heavy snow,” Berisha said during a cabinet meeting on Sunday evening. “We will do everything possible to save the life of citizens and their property."
