Residents of the Kyivsky, Kirovsky, Leninsky and Petrivsky districts in Donetsk woke up to the sound of heavy artillery overnight, says a report posted on the City Hall Web site.

"Tensions persisted in the city as of 0900. The overnight fighting disabled 44 transformer substations in the Petrivsky district and cut power supply to residential buildings in the Petrivsky district and the suburbs of Biriuzova and Hrabari," the report said.

Only two out of 28 disabled transformer stations have resumed operation in the Kuibyshevskyi district as the hostilities are slowing down the repair teams' work.

Water supply is erratic in the Kirovsky, Kuibyshevsky, Leninsky and Petrivsky districts. The Donetskmiskvodokanal administration is working on its stabilization.

Public transport is operating under the weekend schedule.

The online edition Novosti Donbassa said that militants opened fire at the Donetsk Petrivsky district at 0500. Eyewitnesses said it was impossible to bring the Trudivska mine workers to the surface because of the shooting.
