BBC在线收听下载:拜登敦促特朗普公开与乌克兰总统的通话记录

Hello, I'm Tom Watts with the BBC news.

The United States is to send troops and missile defense systems to Saudi Arabia and the United Arab Emirates in response to last week's attack on Saudi oil facilities. Washington has blamed Iran for the attack, but the Iranians insist they were not involved. With more details, here's Frank Gardner.

The multiple drone and missile attacks on Saudi Arabia's oil installations have exposed a major gap in its defenses. Now, the US, its strategic ally, has offered to help plug that gap with a package of defensive measures. The US navy destroyer is being stationed in the northern Gulf to intercept any missiles coming from that direction. The Pentagon has also announced a further deployment of what's been called a moderate number of troops to Saudi Arabia to join those already helping the country bolster its anti-missile defenses.

Hundreds of protesters took to the streets of Cairo and other Egyptian cities on Friday night in a rare sign of opposition to President Abdel Fattah el-Sisi.

Dissent has been repressed since President Sisi took power.

We are doing this to wake the leaders up. We are doing this to get them to act. We deserve a safe future and we demand a safe future. Is that really too much to ask? Millions of people around the world gathered throughout the day.

For much of his presidency, Donald Trump's battled allegations he benefited from a foreign power interfering in the last election. Now he's already fighting claims he's inviting help for the next election not from Russia this time, but Ukraine. It's come to light that the US intelligence official were so disturbed by the thrust of a telephone conversation between President Trump and the Ukrainian president Volodymyr Zelensky that he made a formal complaint. Donald Trump says he's done nothing wrong.
