US President Trump

Trump declares emergency over IT threats

The president signed an executive order effectively barring US companies from using foreign telecoms believed to pose a security risk to the country.

Mr Trump does not name any company specifically in the order.

However, analysts suggest it is mainly directed at Chinese telecommunications giant Huawei.

A number of countries have raised concerns the company's products could be used by China for surveillance.

The Chinese company - which is the world's largest maker of telecoms equipment - has denied that its work poses any risks of espionage or sabotage.

Senate Republicans revolt against Trump over border

Twelve Republican senators broke party ranks to side with Democrats, approving a proposal to revoke the proclamation by 59-41.

The Democratic-controlled House of Representatives last month backed the measure.

Following Thursday's vote, Mr Trump tweeted: "VETO!"

Congress needs a two-thirds majority of both chambers to override a presidential veto, which is viewed as unlikely in this case.

Nevertheless, the vote will be seen as an embarrassing loss for the president on his signature domestic issue.

US and North Korea preparing Trump-Kim summit

The talks in the village of Panmunjom, in the demilitarised zone between the two Koreas, are the latest sign that the summit could take place after all.

On Thursday Mr Trump called off the meeting - due in Singapore next month - citing the North's "hostility".

But both sides have since been working to get it back on track.

On Saturday Mr Kim and South Korean President Moon Jae-in held an unannounced meeting. Mr Moon said the North's leader had "again made clear his commitment to a complete denuclearisation of the Korean peninsula".
