According to reports on a Somali news network, gunmen arrived to close down the cinema in the town of Dhuusa Marreeb in central Galgadud district, where a crowd had gathered to watch the Germany-Italy World Cup semi-final.
Some of the football fans began to protest and according to reports, the gunmen fired in the air in an attempt to disperse them.
When this failed, shots were fired at the demonstrators and two people were killed.
