Ukraine war

At least 17 people, including a child, were killed in the blast, which took place on a busy market street in the middle of the day - a rarity.

Kostyantynivka, in Ukraine's eastern Donetsk region, is near the frontline.

Videos on social media show a bright orange explosion at the far end of a street where people were out shopping. Russia is yet to comment on the attack.

Zelensky, who has blamed Moscow, said those killed were "people who did nothing wrong" - and warned the death toll could increase.

But Mr Putin said the plan could be put forward only when they are ready "in the West and Kyiv".

The Russian leader met Chinese President Xi Jinping on Tuesday in Moscow to discuss the conflict, and relations between the two countries.

BBC reports China's plan, published last month, does not explicitly call for Russia to leave Ukraine.

Listing 12 points, it calls for peace talks and respect for national sovereignty, without specific proposals.

In a statement, the G7 group also said that Russia must stop blocking food from leaving Ukraine's ports.

Addressing the summit via video link, Ukraine's president appealed for more heavy weapons from Western allies.

G7 leaders are under pressure to be united in their approach against increasing Russian aggression.

"We will continue to provide financial, humanitarian, military and diplomatic support and stand with Ukraine for as long as it takes," they said in a strongly worded statement on Monday.

Secretary-General Jens Stoltenberg said the costs of war were high, but the price of letting Moscow achieve its military goals was even greater.

UK Prime Minister Boris Johnson has also warned of a longer-term conflict.

And in a stark warning, the newly appointed head of the British Army said the UK and allies needed to be capable of winning a ground war with Russia.

Many of them are sheltering in bunkers beneath the city's Azot chemical plant.

The last bridge leading out of the city was destroyed in fighting earlier this week - effectively trapping its 12,000 remaining residents inside.

For weeks capturing Severodonetsk has been a top military goal for Russia, which now controls most of the city.

"The lack of water and sanitation is a big worry. It's a huge concern for us because people cannot survive for long without water," spokesperson for the UN's Humanitarian Affairs office Saviano Abreu told the BBC.

The coffee chain will now retreat entirely from the Russian market, after suspending trading there in March.

It said it would continue to pay nearly 2000 staff working at its shops in the country for six months.

Starbucks joins firms such as McDonald's and Renault in permanently exiting the country.

US and Western allies responded to the war by hitting Russia with wide ranging economic sanctions aimed at isolating it economically and cutting it off from the global financial system. The rules make it difficult for Western companies to operate there.

Boris Bondarev, whose LinkedIn says he worked at the Russian mission to the UN in Geneva, told the BBC he knew his decision to speak out may mean the Kremlin now considers him a traitor.

But he stood by his statement which described the war as "a crime against the Ukrainian people" and "the people of Russia".

Moscow has not yet commented.

Russia has cracked down on those who are critical of or veer from the official narrative surrounding the war, which it refers to only as "a special military operation".

The move comes after it temporarily closed its 850 outlets in March.

The fast food giant said it made the decision because of the "humanitarian crisis" and "unpredictable operating environment" caused by the Ukraine war.

The opening of McDonald's first restaurant in Moscow in 1990 came to symbolise a thaw in Cold War tensions.

A year later, the Soviet Union collapsed and Russia opened up its economy to companies from the West. More than three decades later, however, it is one of a growing number of corporations pulling out.
