Zimbabwe's official media says the nation's generals and police commanders won't meet with the prime minister and other "malcontents" trying to undermine their powers.

The state-owned Herald newspaper, controlled by President Robert Mugabe's party, reported Wednesday the country's police chief warned critics of the army and police that they risked being arrested if they continued demanding reforms in the security forces and "peddling lies" on the role of the armed services ahead of crucial elections later this year.

Security chiefs "will neither meet or engage" with Prime Minister Morgan Tsvangirai, the paper quoted police chief Augustine Chihuri saying.

Zimbabwe's security chiefs "have no business talking to individuals of no substance," Chihuri said.

Tsvangirai's party has called for an overhaul of the police and military blamed for openly supporting Mugabe.
