Germany's leaders look at tightening gun controls

Senior German officials have called for tightened gun controls after Friday's deadly shooting in Munich that claimed the lives of nine people and the gunman, an 18-year-old reportedly obsessed with mass killings.

"We must continue to do all we can to limit and strictly control access to deadly weapons," Vice-Chancellor Sigmar Gabriel, leader of the centre-left Social Democrats, told local media on Sunday.

He said authorities were investigating how Ali Sonboly, a German-Iranian who held dual citizenship, had gained access to a weapon despite signs he had significant psychological issues.
