Google has cut phone maker Huawei off from some updates to the Android operating system, Reuters reports.

New smartphones made by the company will also lose access to Google's app store and software such as Gmail, the news agency's story says.

Huawei declined to comment and Google did not immediately respond to a request for comment from the BBC.

What services precisely will be severed is still being discussed at Google, said Reuters, citing an unnamed source.

Huawei can still use the version of the Android operating system available through the open source license.

On Wednesday the Trump administration added Huawei to its "entity list", blocking the sale or transfer of American technology without a licence.
