The White House has condemned the "ridiculous" arrest of a Wall Street Journal correspondent in Russia, who is facing spying allegations that carry a 20-year jail sentence; a nine-missile barrage has destroyed homes in Kharkiv; and sanctions hamper Russian efforts to replace key radar.
Families in the eastern city of Avdiivka will be forced to evacuate next week as fierce fighting continues in the region, the head of the city's military administration has said.
In an interview with Interfax news agency, Vitalii Barabash said there were still around 2,000 people residing in the region, six of whom were children.
Sanctions are undermining Moscow's ability to replace key radar systems destroyed by Ukrainian special forces, according to British military intelligence.
Earlier this month, Ukraine released video of a Russian counter-battery radar being destroyed in the Donetsk area.
The UK Ministry of Defence said today that while replacing it will be a "key priority" for Russia, the system relies on high-tech electronics disrupted by sanctions.
President Joe Biden's administration has condemned the arrest and detention of a US journalist in Russia on suspicion of spying.
Russia's security service opened an espionage investigation into Wall Street Journal reporter Evan Gershkovich, 31, yesterday - a crime that carries a jail sentence of up to 20 years in Russia - and a court quickly ruled he would be kept behind bars pending its results .
Russia's security service alleged he "was acting on instructions from the American side to collect information about the activities of one of the enterprises of the Russian military-industrial complex that constitutes a state secret."
The WSJ "vehemently denies the allegations from the FSB and seeks the immediate release of our trusted and dedicated reporter, Evan Gershkovich", it said.
Russia has been launching drones and missiles against a wide variety of vital infrastructure targets for several months.
The missiles were launched from the southern Russian region of Belgorod, said the governor.
Belgorod lies just across the border to the north of Kharkiv.
Military analysts say Russia has repurposed some S-300s to attack ground targets in Ukraine.
Yesterday, Rafael Grossi, head of the International Atomic Energy Agency (IAEA), said he was putting aside plans for a security zone around the Zaporizhzhia Nuclear Power Plant so he could propose specific protection measures acceptable to both Moscow and Kyiv.
He said he had been pushing for a demilitarised zone at the Russian-held power station and told Russian reporters that the situation was not improving.
A recording of the briefing was made available to Reuters. Ukraine has provided its latest update on the number of losses Russia has suffered since the start of the war.
