Zimbabwe's President Mugabe told crowds at a Heroes' Day celebration earlier this week in the capital, Harare, that people who had killed white farmers during the country's land reform programme should not face prosecution:

Social media users are still reacting to Mr Mugabe's comments:

During the colonial era, the best farmland in Zimbabwe was reserved for the white population and in 2000, Mr Mugabe spearheaded the seizure of the land from some 4,000 white farmers.

Zimbabwe's President Robert Mugabe has previously admitted failures in the country's controversial land reform programme, saying in 2015:

"I think the farms we gave to people are too large. They can't manage them".

The sudden seizure of land from white farmers is seen as a key factor in Zimbabwe's economic meltdown since 2000.

Three female suicide bombers carried out an attack that killed at least 27 people in north-eastern Nigeria, officials say.

Dozens were injured when the women blew themselves up outside a refugee camp near Maiduguri in Borno state, a stronghold of the Islamist militant group Boko Haram.

There has been an upsurge in violence in the city in recent months.

Boko Haram has been fighting to set up an Islamic state since 2009.

A report published by US anti-terrorist researchers last week, external said it is the first insurgency in history to use more women suicide bombers than men.

Baba Kura, a member of a vigilante force set up to fight the jihadists, told AFP news agency on Tuesday that the first bomber blew herself up near the camp, triggering panic.

"People were trying to close their shops when two other female bombers triggered their explosives, causing most of the casualties," he said.

Zambia's opposition leader Hakainde Hichilema, who was facing treason charges, has been released his party has said.

It has shared the news on its Twitter handle:

Mr Hichilema was arrested in April after his motorcade allegedly refused to give way to President Edgar Lungu's as the two leaders headed to a traditional ceremony in western Zambia.

He was accused of endangering the president's life.

The UPND leader along with five of his supporters had been charged with treason which is a non-bailable offence under Zambian law. They "strongly" denied the charge.

A source had earlier told the BBC about the impending release and that it was part of a deal brokered by the Commonwealth:

"He is definitely being released today through a nolle prosequi [dismissal of a case] unless there's a last minute development."

Once a nolle prosequi is entered it means that the prosecution team will no longer prosecute a case, though the suspect may be re-arrested in future on the same case.

Commonwealth Secretary General Patricia Scotland was in Zambia last week and met up with President Lungu and Mr Hichilema.

She later hinted Mr Hichilema could be released in public interest.
