A car bomb has exploded in Russia for the second time in two days. In Moscow, Sergei Zavorotny was injured; he is a former adviser to Mykola Azarov, Ukraine's pro-Russian ex-prime minister, and was taken to hospital. In Saint Petersburg, a car bomb killed a Russian colonel.

The attacks came during a period of informal peace talks in Dublin. At the same time, attacks by both sides continued overnight. Ukrainian authorities reported that a hospital had been hit by Russian shelling, and three people, including a 17-year-old, died in attacks in the south around Odesa and Zaporizhzhia. Russia said a Ukrainian strike on an industrial facility in the Samara region had killed four people, and four more had died in a drone attack on an industrial zone in the Volgograd region.

Zelensky welcomed the US involving Europe in the talks. Jared Kushner and Steve Witkoff spoke to Vladimir Putin in Moscow. Prime Minister Andy Burnham announced that the UK national security adviser Jonathan Powell would take part in the talks, but Downing Street said discussions involving him had been delayed.

• A car bomb in Moscow injured Sergei Zavorotny, a former adviser to Ukraine's pro-Russian ex-prime minister Mykola Azarov.
