Ukrainian officials said Russia launched a large-scale attack with cruise and ballistic missiles, forcing Kyiv to activate a nationwide air defense alert.

The Ukrainian Air Force Command activated a nationwide air defense alert from 6 a.m. today (11 a.m.), warning that a series of Russian cruise and ballistic missiles were targeting the country. The specific target and number of weapons deployed by Russia have not been determined.

Oleksandr Vilkul, mayor of Kryvyi Rih city in Dnipro province, said that many cities were under heavy attack and the extent of damage would only be announced after the raid ended.

Yuriy Malashko, Zaporizhzhia governor appointed by Ukraine, said at least five explosions were heard in the capital of the same name and injured two people. Anatoliy Kurtiev, secretary of the Kiev-controlled city council of Zaporizhzhia, said the attack had caused casualties in the municipality but did not provide specific information.

Ihor Terekhov, mayor of the city of Kharkiv in northeastern Ukraine, said many industrial facilities were raided and set on fire, injuring at least one woman. Military agency officials in the cities of Dnipro and Khmelnytskyi also reported “intense missile attacks” conducted by Russia.

The Russian Ministry of Defense has not commented on the information.

The British military last week determined that Russia was stepping up attacks on Ukraine’s defense industry, unlike the campaign to attack energy infrastructure last winter.

” Russia may have temporarily adjusted its tactics for using long-range offensive weapons. Russian planners have almost certainly recognized the importance of adversary defense industrial capabilities in their efforts to prepare for protracted fighting,” the agency said.

Moscow announced that the targets of its air strikes were defense industry corporations specializing in the production of missiles and UAVs, as well as military equipment repair facilities, missile and ammunition warehouses and aviation weapons donated by the West. Support for Kyiv.
