Officials said that Russian forces launched "double tap" rocket attacks on Saturday against a small village near Ukraine's second-largest city, Kharkiv. Two people were killed, including an official from the emergency services and a policeman.

Four people were also killed in Donetsk, a region in the southeast.

The prosecutors said that the missile attack in the afternoon targeted the Budy railway station, southwest of Kharkiv. A second missile was launched after rescue teams had arrived.

The incident left 23 people injured.

Ihor Klymenko, the Interior Minister, said that the chief of emergency services in the Kharkiv District was killed along with a policeman from a rapid response unit. Three emergency workers, one policeman and around 20 civilians were among the injured.

Russia has denied deliberately targeting civilians. The "double tap" tactics used by Russian forces has had a devastating effect.

Kharkiv was not in Russian hands during the initial advance by the Kremlin forces following the February 2022 invasion.

Since then, the city and its surrounding areas have been constantly attacked. However, Ukrainian officials claim that this has decreased since U.S. weapons supplies to Ukraine were resumed following a hiatus of several months.

Vadym Filashkin, the governor of Donetsk region, said that a rocket attack on a multi-storey building in Chasiv Yar -- a town which Russian forces have targeted as a staging area for their advance through Ukraine's eastern regions -- killed one person.

One person was killed by a guided bomb that is increasingly being used in Russian attacks near the town Kurakhove. This is where the most intense fighting along the 1,000 km (600 mile) front takes place.

Two people were killed by two bombs that were dropped in a village to the west of Komar. A shop and 10 buildings were damaged. (Reporting and editing by Nick Zieminski, Deepa Babington and Oleksander Kzhukhar)
