Two Kenyans and 90 Somalis have been deported from the US over unknown reasons.

The group arrived at the Jomo Kenyatta International Airport, Nairobi and was processed by immigration officials.

Government spokesman Eric Kiraithe confirmed that the group arrived in Nairobi and said he did not know why they had been deported.

“I don’t have details of their deportation but it is true there are 90 Somalis and two Kenyans who arrived at JKIA after deportation from the US,” said Kiraithe.

Kiraithe said authorities were working on taking the Somalis to Mogadishu Wednesday.

Other officials said the number is higher than in past cases and expressed fears American authorities were cracking down on illegal immigrants there.

It came ahead of President Donald Trump’s expected signing of executive orders starting on Wednesday that include a temporary ban on most refugees and a suspension of visas for citizens of Syria and six other Middle Eastern and African countries.

According to Reuters, Trump, who tweeted that a "big day" was planned on national security on Wednesday, is expected to ban, for several months, the entry of refugees into the United States, except for religious minorities escaping persecution, until more aggressive vetting is in place.

Another order will block visas being issued to anyone from Syria, Iraq, Iran, Libya, Somalia, Sudan and Yemen, said the aides and experts who asked not to be identified.
