One person was killed and 15 hurt when a minibus collided head-on with President Robert Mugabe’s motorcade in Zimbabwe.

The crash, which happened on Sunday on the Robert Mugabe highway near the president's home town of Zvimba, is the third lethal accident involving the leader’s motorcade in just two weeks.

The latest is being blamed by officials on the driver of the bus, who it’s claimed didn’t take avoiding action quickly enough, despite sirens being sounded.

Mugabe’s escort normally contains around 10 vehicles with the president riding in a limousine.

In this instance the leading police car smashed into the bus, leaving one of the passengers fatally injured.

"The driver of a commuter minibus failed to heed the siren and beacon of the escort vehicle resulting in a head-on collision between the minibus and the police vehicle," National police spokesman Wayne Bvudzijena told AFP.

"One passenger in the commuter bus died on the spot while 15 passengers from both vehicles were injured in the accident."

Two weeks ago, also in Zvimba, a motorbike in the presidential cavalcade hit and killed a mentally disabled man.

In a separate accident on the same trip, a member of the presidential guard died and seven others were injured when a burst tyre caused a truck in the motorcade to overturn.
