KENYA will close its airspace for a 50-minute window ahead of United States (U.S.) President Barack Obama’s arrival in the capital, Nairobi today, the country’s Civil Aviation Authority (KCAA) said.

A ban on planes flying lower than 20,000 feet will remain in place in Nairobi for the duration of Mr. Obama’s three-day visit, it said.

Some U.S. media have criticised the KCAA for revealing Mr. Obama’s travel plans.

The U.S. issued a travel warning for Kenya in July ahead of the visit.

Meanwhile, the country’s Interior Minister, John Nkaissery, has called on U.S. news channel, CNN, to apologise for calling East Africa a “hotbed of terror” ahead of President Obama’s visit today.

It would make an apology “if it was civilised enough”, Mr. Nkaissery said at a news conference.

The hashtag #SomeoneTellCNN is trending worldwide as Kenyans condemned CNN, which has not yet commented.

Its report focused on the threat posed by the al-Qaeda linked al-Shabaab group.

Mr. Obama was “not just heading to his father’s homeland, but to a region that’s a hotbed of terror”, said the CNN report.

The global entrepreneurship summit in Nairobi this weekend, which Mr. Obama is due to address, could provide “a target for terrorists”, the U.S. State Department said in a statement.

Kenyans are preparing for significant disruption after police announced major road closures in Nairobi from today.

Kenyan airspace will also be closed for a further 40 minutes on Sunday when President Obama leaves for neighbouring Ethiopia.

Somali’s Islamist group, al-Shabaab, has staged repeated attacks on Kenya in recent years.

In April, it killed 148 people at a university in the north and in 2013, at least 67 people died when the al-Qaeda-linked group attacked Westgate shopping centre in Nairobi.

Last month, the United Kingdom lifted its warning against travelling to part of Kenya’s coast, including Mombasa.

Mr. Nkaissery said Kenya was at risk of attack like any other country, but this did not turn it into a “hotbed of terror”.

“I urge Kenyans to treat the @CNN report with the contempt it deserves,” he said, according to a tweet by Kenya’s privately owned Daily Nation newspaper.

CNN quoted security analyst, Seth Jones, as saying that al-Shabaab could carry out an attack during Mr. Obama’s visit.

“Security for the president is likely to be very significant and that means what Al-Shabaab is likely to do, based on what it has done very recently, is go for a soft target,” he said.

On Twitter, Kenyans criticised the report.
