Mugabe's New Land Grab and Rare Wildlife on Menu.

Zimbabwean president Robert Mugabe has celebrated his 91st birthday with a lavish million-dollar bash that was slammed by the opposition as "obscene" in a country wracked by poverty.

Thousands of supporters of the ruling ZANU-PF, many wearing party regalia emblazoned with the president's image, sang and danced as he arrived for the jamboree at a luxury hotel in the famed Victoria Falls resort.

The elderly liberation leader threw 91 balloons into the air.

The party, which came a week after Mr Mugabe's birthday, was held on the hotel golf course, with white marquees housing the guests.

Elephants were slaughtered for the feast and seven huge cakes were on display in one of the tents.

One giant, 91-kilogram creation depicted the spectacular Victoria Falls, which empty into the Zambezi river that forms the border between Zimbabwe and Zambia.

Addressing the gathering in a 90-minute speech, Mr Mugabe castigated the US which had imposed sanctions on both Zimbabwe and him personally.

"[The US] can't have it both ways. If they want to be friends then they must be friends with us in total and we allow them to have some safaris," he said.

"But they can't say 'allow our people to visit, allow our people to have safaris, to kill our lions and take safari trophies to America'."

Mugabe also believes blacks are now better equipped to run more farms and has signalled he will be seizing more white farms and wildlife parks and evicting the white owners
