Russia launches a deadly attack on the city of Lviv in western Ukraine

Russian missiles hit downtown Lviv early Thursday, causing at least four deaths and nine more injuries. Lviv, a refuge for Ukrainian civilians fleeing the war in the east, is considered largely out of harm's way. Ukraine's air force said the direction of the missile barrage was deliberate. The missiles also launched an airstrike deep inside Russian-held territory in the eastern Donetsk region. The strike hit a residential neighborhood in the Russian-occupied city of Makiivka, but Ukrainian officials say secondary explosions right after the missile struck prove it was a direct hit on a Russian weapons depot. On the front line, there is the renewed specter of a possible nuclear disaster at the Zaporizhzhia Nuclear Power Plant. Both sides have accused each other of plotting to sabotage the Russian-occupied facility, which is the largest nuclear power plant in Europe. IAEA inspectors have been at the plant for weeks and demanded unlimited access to all parts of the compound to confirm the absence of mines or explosives at the site. Regional officials told CBS News that the IAEA experts were being blocked from some parts of the nuclear plant by Russian forces who control it. In the nearby city of Zaporizhzhia itself, government officials have warned residents to prepare for a nuclear emergency.
