Intense artillery fire in Ukraine’s rebel bastion Donetsk

Ukraine’s separatist bastion of Donetsk came under intense artillery fire early Sunday, in a level of combat not seen in the region since a barely-observed ceasefire was signed in September.
Firing close to the centre of Donetsk began to build up at 2am, and could still be heard at the same intensity two hours later.
However it was not immediately possible to evaluate the consequences of the artillery bombardment due to an overnight curfew imposed by the rebel authorities in Donetsk and nearby Makiivka.
The Organisation for Security and Cooperation in Europe (OSCE) voiced concern Saturday after its monitors witnessed unmarked columns of tanks and troop carriers moving through east Ukraine in territory held by pro-Russia separatists.
The OSCE report came a day after Ukraine’s military said it had spotted a large column of tanks and other heavy weapons entering the country from Russia across a section of border that has fallen under control of rebel fighters.
Russia denies being involved in the fighting in the east.
