South African police say they are investigating opposition leader Julius Malema for "reckless and inflammatory" speech, reports the Reuters news agency.

He told Al Jazeera news , externalthat the opposition "will run out of patience very soon and we will remove this government through the barrel of a gun" if the ruling African National Congress continues to respond violently to peaceful protests.

US Embassy in Juba has been relaying the comments on its Facebook page, external of South Sudan's vice-president designate Riek Machar just after he arrived in the capital.   

We've already mentioned that he talked about getting a permanent ceasefire and stabilizing the economy, but the US Embassy writes that he also said that "we need to reach out to displaced people to ensure humanitarian access".  

Meanwhile, journalists have been tweeting pictures of the arrival of Mr Machar:

She says: "Huge celebrations in the Juba Protection of Civilians site with the news IO leader Riek Machar has returned."

South Sudan's rebel leader was surrounded by dozens of dignitaries and journalists as he got off the plane in the capital, Juba.

One photographer managed to grab a shot of him:

Journalists have been tweeting some of his comments:

Riek Machar's return is extremely significant and can be seen as a sizeable step forward in the peace process. 

The government is due to implement the peace deal signed last year, agree on a constitution, and prepare the country for elections within 30 months. 

When the government is formed donors will start stumping up money - crucial as the economy is at rock bottom.

However, it is not necessarily the end of the conflict. 

The army and Mr Machar's forces have continued to clash, despite the August ceasefire. 

And there are rebel groups not aligned to Mr Machar which have not signed the peace deal.

It is also a power-sharing deal that brings the country back to the way the government was set-up shortly before the civil war began.

South Sudan rebel leader Riek Machar has arrived in Juba:

We have been here before... but all the signs are that South Sudan rebel leader Riek Machar is finally in his way to the capital, Juba, to take up his post as first vice-president in a new unity cabinet.

This is seen as a key move in bringing an end to the more than two-year-long civil war.

Two Juba radio stations are tweeting about what's being seen at the airport:

If reports from South Sudan Tribune and the UN mission in South Sudan are true, South Sudanese rebel leader Riek Machar should be landing very soon in the capital, Juba.

Here's why this is so highly anticipated.

Firstly, his arrival had been promised then cancelled a few times.  

He had been due on Monday 18 April.

His team said the delay was caused by logistical and administrative issues and that he planned to return on Wednesday.

A statement from the government on Tuesday had said Mr Machar's return was delayed as "he wanted to come with an arsenal of arms... anti-tanks, laser guided missiles and heavy machine guns".

Secondly, people are waiting for him to take up the post of first vice-president in a new unity government.

This is a key part of the peace agreement signed in August 2015 which ended nearly two years of conflict.

An estimated 2.2 million fled their homes during conflict.

These tweets suggest it is likely that the South Sudanese rebel leader Riek Machar may arrive in the capital Juba today:

The rebel leader has been waiting to depart from the Ethiopian town of Gambella to Juba for more than a week. He is due to become vice-president in a unity government to end more than two years of civil war.

South Sudanese and international journalists have been waiting for over a week for the rebel leader Riek Machar to arrive in the capital, Juba. 

But now there are some indications that he could be on his way.

Which means the tripods are out in anticipation:

Let's wait and see if they will be put to use.

Asha - not her real name - says she was forced to marry a man much older than her by her family who wanted the money he would give them.

She was told that if she didn't marry him she could not live in the family house.

She said he beat her and mistreated her:

She became pregnant and now lives in a hostel in Shinyanga in northern Tanzania, where 68 other child brides live.

Save the Children are calling on the Tanzanian government to set the minimum age of marriage at 18.

The sense of expectation is building that South Sudan rebel leader Riek Machar is about to return to the capital, Juba, to take up the post as first vice president in a new unity government.

We had this same feeling last week and he didn't show up but there are reports (see 11:47 entry) that he is on his way.

And Canada's ambassador to South Sudan has tweeted his excitement that this might really be it: 

Kenyans are mourning the death of the former first lady Lucy Kibaki using the hashtags #RIPMamaLucy and other variations to express their feelings.

Mrs Kibaki, who was born in 1940, had withdrawn from public life during the latter part of her husband's rule, which ended in 2013.

She was last seen at a public function was in August 2010, when she seemed excited about the adoption of a new constitution, dancing to a famous gospel song, Kenya's Daily Nation newspaper reports.

Mrs Kibaki sparked controversy after slapping a journalist angry at the way a story about her was reported.

This tweet suggests South Sudanese rebel leader Riek Machar has finally boarded his plane to the capital, Juba:

Once he arrives he is meant to take up his position as first vice president, as agreed in a peace agreement.

But he has cancelled multiple plans previously to fly.

Nigeria's Economic and Financial Crimes Commission (EFCC) has announced the fraud conviction of a former Kogi state assembly member Gabriel Daudu.

He was alleged to have stolen $7m (£4.8m).

In a statement, the EFCC says he was found guilty of "77 counts and sentenced him to 154 years imprisonment".

But each count carries a two-year sentence and the judge ruled that he will serve them concurrently, so will only spend a maximum of two years in prison.

South African former cricketer Jaques Kallis is in the middle of a Twitter storm following his reaction to Sport Minister Fikile Mbalula's decision to ban some sporting codes from hosting international tournaments because of a lack of transformation. 

Some sports, including rugby and cricket, are often criticised for being "too white" more than 20 years since the end of white minority.   

On Monday Kallis tweeted:

 A South African writer responded:

And a South African sports reporter has also hit out:

Ex-cricketer Allan Donald also tweeted his criticism of the sports minister's decision - but that has since been deleted:
