Russian artillery pounds southern city three times overnight, governor says; Zelenskiy warns negotiations not possible if trial goes ahead.
Turkish President, Tayyip Erdogan, is planning to speak with his Russian counterpart Vladimir Putin this week to discuss the situation at the Zaporizhzhia nuclear plant and the war in Ukraine, Russian state media agency RIA Novosti cites a diplomatic source as saying.
Erdogan said that he intends to discuss with Putin the results of his talks with Zelenskiy and UN Secretary General António Guterres in Lviv , as well as to ask the Russian president to take specific measures to resolve the situation at the Zaporizhzhia plant.
According to RIA Novosti, the source said:
Yes, such negotiations are expected this week. [Putin] outlined the topics earlier. This is the situation at the Zaporizhzhia nuclear power plant and the settlement of the Ukrainian crisis in general. Turkey continues to play its honest mediating role in this conflict, being the only country that has won the trust of both sides."
In case you missed this earlier report, here is a quick recap by the Guardian's Moscow correspondent, Andrew Roth.
Darya Dugina, the daughter of an ultranationalist Russian ideologue and ally of Vladimir Putin, was killed in a car bomb on the outskirts of Moscow on Saturday night.
Dugina, whose father is the Russian political commentator Alexander Dugin, died when the Toyota Land Cruiser she was driving was ripped apart by a powerful explosion about 12 miles (20km) west of the capital near the village of Bolshiye Vyazemy at about 9.30pm local time (1930 BST), according to investigators.
Prominent Russian hawks without evidence quickly blamed Kyiv for the attack, calling it an assassination attempt and demanding the Kremlin respond by targeting government officials in Kyiv.
If the car bombing is tied to the war it would mark the first time since February that the violence unleashed on Ukraine has reached the Russian capital, touching the family of a Kremlin ally near one of Moscow's most exclusive districts.
Kyiv strongly denied the allegations. "Ukraine has absolutely nothing to do with this, because we are not a criminal state like Russia, or a terrorist one at that," Mykhailo Podolyak, an adviser to the president, Volodymyr Zelenskiy, said in remarks broadcast on television.

Up to 2,000 people are without electricity."

Ukraine's president, Volodymyr Zelenskiy, has warned Russia against putting Ukrainian soldiers captured during the siege of Mariupol on trial, claiming it will risk the possibility of negotiations.
In his latest video address, president Volodymyr Zelenskiy said that if the "absurd and disgusting trial" of Ukrainian soldiers takes place in Mariupol it will eliminate the possibility of talks with Russia.
If this despicable court takes place, if our people are brought into these settings in violation of all agreements, all international rules, there will be abuse. This will be the line beyond which no negotiations are possible."

Repeated shelling has rocked the southern Ukrainian city of Nikopol, located near the Zaporizhzhia nuclear plant, its governor has said.
Zelenskiy warned Moscow against going ahead with the trial of captured Ukrainian soldiers in his latest national address.
It is 7.30am in Ukraine. Here is everything you might have missed:

Russian missiles hit targets near Odesa, Ukrainian officials said. Five Russian Kalibr cruise missiles have been fired from the Black Sea at the region, the regional administration spokesperson said on Monday, citing information from the southern military command. Two were shot down by Ukrainian air defences and three hit agricultural targets, but there were no casualties. Russia said on Sunday the missiles had destroyed an ammunition depot containing missiles for US-made Himars rockets, while Kyiv said a granary had been hit.

A former member of Russia's Duma has claimed that Russian partisans were allegedly behind the car bomb attack. Ilya Ponomarev, who was expelled for anti-Kremlin activities, alleged the explosion was the work of the National Republican Army, which he claimed was an underground group working inside Russia and dedicated to overthrowing the Putin regime. "This attack opens a new page in Russian resistance to Putinism," he said.
Zelenskiy warned Russia against putting Ukrainian soldiers captured during the siege of Mariupol on trial. "If this despicable court takes place, if our people are brought into these settings in violation of all agreements, all international rules, there will be abuse," he said in a Sunday evening address. "This will be the line beyond which no negotiations are possible."
The leaders of Britain, France, Germany and the US urged military restraint around the Russian-held Zaporizhzhia nuclear plant in Ukraine. In a phone call, the four leaders also called for a "quick visit" to the nuclear site by independent inspectors of the International Atomic Energy Agency, according to German chancellor Olaf Scholz's spokesperson.
Four more ships carrying food left Ukraine's ports, Turkey's defence ministry said, bringing the total number of vessels to leave Ukraine's Black Sea ports under a UN-brokered grain export deal to 31.
