Police in Somalia have classified a particular kind of ant as a drug, after discovering that people were steaming the insects and inhaling their vapour to get high.

Odorous house ants, whose scientific name is tapinoma sessile, are known to contain formic acid.

There are accounts of birds appearing "drunk" after eating large quantities of these ants, and a security officer has told TV station Somali Cable that humans are deliberately using it to similar effect.

"They cut off the ants' bottoms, then they put them in the pan with the lid on - after it's boiled for a while people sit around and hover over it, and they get high," he says in the clip below.

When the presenter asks "is this real?" He replies, "yes - then they become light-headed".

He even suggests that there is now a "shortage" of these ants because people are going out and looking for them.

Doctors, however, warn that coming into contact with formic acid can cause dizziness, nausea and vomiting.

So, don't try this one at home.

Somalis are dying from climate-induced drought fuelled by other nations' consumption, one of the country's top officials says.

Abirahman Abdishakur, the president's special envoy for drought response, told BBC Weekend that Somalia is now facing its fifth, failed rainy season in October.

More than half of Somalia’s population is at serious risk of famine over the next two months unless aid is immediately increased, the UN warned recently.

It has appealed for nearly $1bn (£831m) but Somalia says it has only received a fraction of that.

Mr Abdishakur told the BBC that events in Ukraine and other global geo-political tensions are "overshadowing" the drought crisis in the Horn of Africa.

Deforestation, and al-Shabab's activities depriving citizens of their livelihoods, were also key challenges facing Somalia, he said.

He says he will consider "running for another 20 years" after 22 years in office already.

The Rwandan leader, Paul Kagame, says he will stand for president again at the next election in 2024.

In an interview with a French TV channel, the 64-year-old said he would "consider running for another 20 years".

"Elections are about people choosing," he added.

In 2015 Mr Kagame changed the constitution allowing him to remain in power until 2034.

In the last presidential election five years ago, official figures showed he won 99% percent of the vote - which many outside of the country dismissed as a sham.

President Kagame fiercely defended Rwanda's record on human rights at a Commonwealth summit in the capital Kigali in June.

Tunisia's President Kaïs Saïed has published amendments to his draft constitution - in an attempt to counter some of the criticism the document faced when it was published last week.

Articles directing the state to work to achieve the objectives of Islam now add "within a democratic system".

It also slightly strengthens constitutional freedoms.

Critics say the changes are minor and will not substantially limit the sweeping powers Mr Saïed plans to give himself, after sacking the government and suspending parliament last year.

The new constitution will be put to a referendum later in July.

The legal expert who oversaw the constitution's drafting says the final document is completely different from what his committee proposed, and could pave the way to dictatorship.
