A second white farmer has been shot dead in Zimbabwe, as the troubled country commemorates 20 years of independence.
The death came hours before President Robert Mugabe addressed the nation to mark the 20th anniversary of Zimbabwean independence - amid his country's deepest political crisis in its history.
Mr Mugabe said he was determined to resolve "for once and for all" the question of land which has sparked recent violence, with squatters moving onto white-owned farms.
But he gave no indication that his supporters should vacate the land they have occupied.
The president's speech also failed to set a date for the parliamentary elections, which he has previously said would happen some time during May.
Trapped
Early on Tuesday, farmer Martin Olds died after being trapped and wounded on his farm in Nyamandhlovu near Zimbabwe's second city of Bulawayo in the south-west of the country.
Another farmer, David Stevens, was shot dead at the weekend. At least five other opposition activists have been killed in recent weeks.
Mr Olds telephoned a neighbour on Tuesday morning, first saying his farm house had been surrounded by 30 to 40 veterans and it "looked pretty serious".
"He phoned later to say he had been shot and could we call an ambulance," the neighbour said.
A neighbour and an ambulance crew who came to Mr Olds's assistance were unable to reach him, and he died shortly afterwards.
Mac Crawford, the head of the Commercial Farmers' Union in the Bulawayo area, told the Zimbabwean paper the Daily News that the government had been arming the veterans in his area.
He said there had been numerous sightings of weapons, but offered no proof of the government's involvement.
'Rhodesian attitudes'
Mr Mugabe's address took a less confrontational stance than some of his recent remarks against white farmers, but gave no indication that the squatters should vacate occupied land.
He emphasised that his government was opposed to racism, and rejected the "persistence of vested attitudes from the Rhodesian yesteryear".
"We understand the frustration of the veterans and the pressures on commercial farmers," the president said.
But he described the "emotive and vexed" land issue as "the last colonial question which heavily qualifies our sovereignty".
"We are determined to resolve it for once and for all," he said.
Mr Mugabe said Zimbabwe's history of racial reconciliation was a "priceless export" which had been an example to Namibia and South Africa as those countries moved to majority rule.
Zimbabwean television broadcast a programme of popular Zimbabwean music in the run-up to the presidential address - which was originally scheduled for earlier on Tuesday morning.
Many of the singers wore combat uniforms and brandished automatic weapons as they sang lyrics commemorating the struggle against white rule in the then Rhodesia.
But public anniversary celebrations were cancelled.
