Oleg Kryuchkov, who is an advisor to the Russian-appointed government in annexed Crimea, has told the RIA Novosti news agency that the occupied Kherson and Zaporizhzhia regions have switched to using Russian mobile communications and internet networks. It quotes him saying:

Another terrorist attack in Kyiv brought down communications in the Kherson and Zaporizhzhia regions. Russia played ahead of the curve. In the liberated territories, it is now exclusively Russian internet and communications. In fact, this is the end of Ukrainian propaganda, Zelenskiy’s towers of lies have fallen.

French journalist is killed near Sievierodonetsk; EU leaders fail to agree on a Russian oil import ban

• Russia-Ukraine war: latest updates

A French journalist, Frédéric Leclerc-Imhoff, was killed after an evacuation car was hit near the Ukrainian city of Sievierodonetsk. The French president, Emmanuel Macron, said: “I share the pain of the family, relatives and colleagues of Frédéric Leclerc-Imhoff, to whom I send my condolences.”

EU leaders failed to agree on a Russian oil import ban before the two-day summit in Brussels. While the leaders of the 27 countries will agree in principle to an oil embargo, the details of their draft conclusions are yet to be decided.

Russia will stop supplying gas to the Netherlands as of tomorrow after the government-backed trader GasTerra refused to pay supplier Gazprom in roubles. About 44% of Dutch energy usage is based on gas, but only about 15% of Dutch gas comes from Russia, according to government figures.

Russia is considering paying Eurobond holders by applying the mechanism it uses to process payments for its gas in roubles. The scheme would allow Moscow to pay bondholders while bypassing western payment infrastructure. Investors, however, said the move would not enable Russia to avoid a historic default on debt.

In talks with the Turkish president, Recep Tayyip Erdoğan, the Russian president, Vladimir Putin, said if sanctions were lifted, then Russia could “export significant volumes of fertilisers and agricultural products”.

The new US ambassador to Ukraine has arrived in Kyiv, the Guardian understands, a symbolic move after the US withdrew all diplomats from the country before the Russian invasion in February.

The US president, Joe Biden, has said the US will not send Ukraine rocket systems that can reach into Russia. The comments followed reports that the Biden administration was preparing to send advanced long-range rocket systems to Kyiv.

Russian troops have entered the outskirts of the Ukrainian city of Sievierodonetsk. Regional governor Serhiy Gaidai has described the fighting as “very fierce”. Gaidai has also appeared on national television in Ukraine to say “Unfortunately we have disappointing news, the enemy is moving into the city.”

“Some 90% of buildings are damaged. More than two-thirds of the city’s housing stock has been completely destroyed. There is no telecommunication,” Ukrainian president Volodymyr Zelenskiy said in a televised speech last night about the status of Sievierodonetsk.

The “liberation” of the Donbas was an “unconditional priority” for Moscow, Russia’s foreign minister said on Sunday, adding that other Ukrainian territories should decide their future on their own. “The liberation of the Donetsk and Luhansk regions, recognised by the Russian Federation as independent states, is an unconditional priority,” Sergei Lavrov told French TV channel TF1.

Lavrov also denied speculation that President Vladimir Putin is ill. Lavrov said that Putin, who will turn 70 in October, appeared in public “every day”.
