Russia and Ukraine resumed talks via video link on Monday morning.
The negotiations wrapped later in the day, and they were expected to start up again Tuesday.
An official taking part in the talks said Ukraine's objectives were to secure a cease-fire, the immediate withdrawal of Russian troops from Ukraine and security guarantees.
The discussions come after a Russian shelling attack on a residential building in Kyiv's Obolon district killed two civilians and injured three, according to Ukrainian authorities.
Anti-war protester in studio disrupts live Russian state TV news
An anti-war protester interrupted a live news bulletin on Russia's state TV Channel One on Monday, holding up a sign behind the studio presenter and shouting slogans denouncing the war in Ukraine.
The sign, in English and Russian, read: "NO WAR. Stop the war. Don't believe propaganda. They are lying to you here." Another phrase, which looked like "Russians against war", was partly obscured.
The extraordinary act of dissent took place on day 19 of the war which began when Russia invaded Ukraine on Feb. 24 in what it calls a special military operation.

Deputy Treasury Secretary Wally Adeyemo discusses sanctions against Russia
Putin's Ukraine war will erase decades of Russian economic growth
Putin's invasion of Ukraine will set the Russian economy back 30 years and erase decades of gains made in moving its citizens into the global middle class, experts told CNBC this week.
After decades of opening its economy to the West, the recent exodus from Russia of global brands will trigger a profound shift in how middle-class citizens make and spend their money.
As the country’s economy collapses under the weight of unprecedented international sanctions, the ruble has lost around 40% of its value against the dollar.
This economic fallout could also create domestic political problems for President Vladimir Putin.
Experts believe the standard of living in Russia will plummet in the next five years, raising questions about whether voters will become disillusioned enough with Putin to challenge his absolute authority.

Erdogan says it would be "premature" for Turkey to stop buying Russian arms
Turkish President Recep Tayyip Erdogan did not rule out buying additional Russian weapons despite Moscow's war in Ukraine.
Erdogan, who spoke alongside German Chancellor Olaf Scholz, said Ankara would continue to meet its NATO commitments to Ukraine but that it would be "premature" to cancel future weapons agreements with Russia.
"Under the current circumstances, it would be premature to talk about what the future shows right now. We have to see what the conditions bring," Erdogan said on Monday. "We have to maintain our friendship with Mr. Zelenskyy and Mr. Putin," he added.
In 2017, Erdogan brokered with Russian President Vladimir Putin a reported $2.5 billion deal for the S-400 missile system. The S-400, a mobile surface-to-air missile system, is said to pose a risk to the NATO alliance as well as the F-35 aircraft, America's most expensive weapons platform.
Despite warnings from the United States and other NATO allies, Turkey accepted the first of four missile batteries in July 2019. The Trump administration cut Turkey, a financial and manufacturing partner, from the F-35 program and imposed sanctions on the NATO ally.

Biden may travel to Europe in the coming weeks
The White House is considering a presidential trip to Europe in the coming weeks, multiple outlets reported Monday, citing anonymous sources.
A visit by President Joe Biden would amplify the effort to shore up American alliances in Europe as Russia's brutal invasion of Ukraine escalates.
Since the start of Russia's unprovoked attack on Ukraine in late February, Biden has played a leading role in marshaling NATO allies and G-7 countries to counter Russian President Vladimir Putin using a combination of economic sanctions and military deterrence.
If he were to visit Europe, Biden would lik
