Artillery shells slammed into the outskirts of the Ukrainian city of Donetsk on Sunday as government forces tightened the noose around the rebel-held redoubt and called on pro-Russian separatists to surrender, Reuters reported. Talk of a ceasefire, a possibility raised by a separatist leader on Saturday, evaporated as Kiev government forces kept up an offensive to crush the rebels. There would be no truce while the Ukrainian army continued "punitive" military action, the rebels reported in a statement. -- SPA 20:12 LOCAL TIME 17:12 GMT تغريد
