Mozambican President Filipe Nyusi has sacked the national defence minister, Jaime Augusto Neto.

It comes just a day after the president fired the interior minister, Amade Miquidade.

The president has not explained why he has fired the country's top defence and security leaders.

It’s believed that the decision has to do with the increased cases of kidnapping, murder, terrorism and corruption, as well as a rising number of road accidents.

Some of the cases have involved members of the defence and the security forces.

Observers have called on President Nyusi to explain his decisions to avoid public speculation, fear and disorder.

They say it's not normal to sack two top security leaders in days and that there must be a reason.
