KYIV — Russia launched a record 728 drones against multiple Ukrainian cities overnight, the Ukrainian air force said on Wednesday.

Defence systems destroyed 718 of the drones and seven cruise missiles, the air force posted on Telegram, in what appears to be one of Moscow's largest assaults on Ukraine in Russia's all-out war.

Dozens of Russian attack drones and ballistic missiles targeted regions in Ukraine's far west, with overhead drones reported in the cities of Lutsk, Lviv, Khmelnytskyi and Ternopil.

The western city of Lutsk was hit hard in the attack, according to local media, with explosions heard in the early hours of Wednesday morning.

The governor of Volyn Oblast, Ivan Rudnytskyi, said "nearly everything" was aimed at Lutsk, which faced 50 drones and five missiles in its airspace overnight.

In Kyiv, Mayor Vitali Klitschko announced Russian drones were attacking the city centre and air defences were shooting down targets.

At least one person was injured in the city of Brovary in the wider Kyiv area, according to the regional military administration. — Euronews
