"Russia has turned the Ukrainian sky into a source of death for thousands of people," Zelensky said in his virtual address before showing video containing graphic images of death and destruction in Ukraine that ended with "close the sky over Ukraine."

Zelensky continued his push for the imposition of a no-fly zone over Ukraine and asked for more planes and defence systems to respond to a Russian invasion launched last month that has caused large-scale destruction in his country and has unleashed a wave of refugees. He also called for more economic sanctions against Russia.

This latest hearing is the first since the storming of the US Capitol.

Politicians believe that was a tipping point for greater regulation.

They have said they plan to change the legislation that protects online platforms from liability for content posted by third parties.

The session began in combative style with the chair Mike Doyle asking all three executives whether they felt they bore responsibility for the events in Washington. None were prepared to give a one word "yes" or "no" answer as he demanded.

The United Airlines boss was called before a hearing of the House Transportation committee Tuesday over the violent removal of an airplane passenger and the bungled apology that followed.

The woman was not shot, Washington Metropolitan Police spokesperson Rachel Reid told the BBC, and no injuries have been reported.

She was taken into custody and the incident prompted a lockdown at one of the Congress buildings.

The incident follows driving attacks last week in London and Brussels.

Capitol Police spokeswoman Eva Malecki said the suspect is a woman, and the incident is "criminal in nature with no nexus to terrorism".

The incident occurred after officers observed an "erratic and aggressive driver" and tried to pull her car over.

The request came a day after President Donald Trump alleged, without supporting evidence, that then-President Obama ordered a wiretap of the phones at Trump's campaign headquarters in Trump Tower in New York.

Mr Trump, who has been facing intense scrutiny over alleged Russian interference in support of his presidential bid, made the wire-tapping allegation in tweets written from his weekend home in Florida early on Saturday.

His press secretary said the inquiry into alleged Russian interference should also examine these allegations.

Adopting a more measured, upbeat tone, the Republican president spoke of a "new chapter of American greatness".

Mr Trump condemned recent vandalism of Jewish cemeteries and a hate crime in Kansas that left an Indian man dead.

His primetime address sought to bolster his low approval ratings after a bumpy start to his fledgling presidency.

At the outset of Tuesday night's hour-long speech, Mr Trump tackled recent suspected hate crimes, saying "we are a country that stands united in condemning hate and evil in all its very ugly forms".

"Recent threats targeting Jewish Community Centers and vandalism of Jewish cemeteries, as well as last week's shooting in Kansas City, remind us that while we may be a nation divided on policies, we are a country that stands united in condemning hate and evil in all its very ugly forms," he said.

He entered the House chamber to thunderous applause as he seeks to pull off a dramatic recasting of his political fortunes. He's delivering the speech just hours after throwing a curveball at his Republican allies by suggesting a shift of his stance on immigration policy.

In the first veto override of his presidency, the Senate voted 97-1 and the House of Representatives 348-77, meaning the bill becomes law.

Mr Obama told CNN the lawmakers had made "a mistake".

The president argued the bill could expose US companies, troops and officials to potential lawsuits abroad.

CIA Director John Brennan said the vote carried "grave implications" for national security, adding: "The downside is potentially huge."
