A petrol bomb hit the home of top Zimbabwe opposition official and former finance minister Tendai Biti, a party spokesman said, the second such attack in three years.

Harare - Zimbabwe’s finance minister says elections won't be held this year because there isn't enough money available.

Minister Tendai Biti told reporters Wednesday his ministry only has cash for a nationwide census in August and a referendum on a new constitution scheduled around the same time.

President Robert Mugabe has called for elections this year to end a fragile three-year coalition with the former opposition of Prime Minister Morgan Tsvangirai. The coalition was formed in 2009 after disputed and violent elections in 2008.

Mugabe has insisted that “money has to be to found” for elections to go ahead this year, with or without a new constitution. Tsvangirai says elections can only be held after constitutional and election reforms are complete. - Sapa-AP
