Russian strikes on Ukraine overnight killed at least four civilians and wounded 20 others, according to President Volodymyr Zelensky, who is navigating a political crisis after dismissing his popular defence minister, Mykhailo Fedorov.

The sudden reshuffle of Zelensky's government, including the appointment of a new prime minister, has unsettled Ukraine's military leadership and sparked public outrage.

Fedorov, known for driving Ukraine's technological innovations and anti-corruption efforts, was replaced due to tensions with Defence Forces Commander Gen Oleksandr Syrskyi.

Zelensky has tasked Maj-Gen Yevhen Khmara, a respected special operations expert, to temporarily oversee defence duties, though his formal appointment faces bureaucratic delays.Meanwhile, Russian attacks continue to target civilian areas, with strikes in Odesa, Zaporizhzhia, and Kharkiv causing additional casualties.Moscow claims its air defences downed 243 Ukrainian drones, while Ukraine reports civilian casualties from its drone strikes.The conflict underscores the escalating tensions and challenges facing Ukraine's leadership amid ongoing warfare.
