Ukraine Demands Rebels Surrender as Fighting Rages in Donetsk by VOA News A Ukrainian military spokesman rejected a pro-Russian separatist call for a cease-fire, as fighting continues unabated in eastern Ukraine. Ukrainian troops have surrounded Donetsk in a "tight ring" and the only thing for rebels left to do is surrender, said Andriy Lysenko, the Ukrainian National Security and Defense Council spokesperson, on Sunday. Lysenko said the rebels announced late on Saturday that they were ready to agree to a cease-fire to prevent a "humanitarian catastrophe." However, Lysenko said, "There has only been a statement" but no practical steps by the rebels to prove that they were ready for a cease-fire. Donetsk fighting Fighting raged around the Ukrainian city of Donetsk Sunday morning. In Kievsky district, 6 kilometers west of the city center, black smoke was rising above headquarters of Ukrainian telecommunication company "Ukrtelecom." A nearby apartment block was damaged as well, with many windows shattered and balconies destroyed. Elsewhere, Russian Foreign Minister Sergei Lavrov said on Sunday Moscow was in talks with Kyiv, the International Committee of the Red Cross and the United Nations on sending humanitarian aid to eastern Ukraine. "We think it is a priority now to reach an agreement with the Ukrainian side, International Committee of the Red Cross and the international U.N. humanitarian agencies on the necessity to send emergency humanitarian aid to the (eastern Ukrainian provinces) of Luhansk and Donetsk," Lavrov told reporters. The rebel leader's motive for offering a cease-fire was not clear, but his comments could be aimed at increasing the pressure on Ukraine to allow in a Russian aid mission. Russia, which the Ukrainian government in Kyiv and Western countries allege is supporting the rebels, has called repeatedly for a humanitarian mission into eastern Ukraine. But Kiev and the West suggest that could be just a pretext to send Russian forces into the region - and say about 20,000 of them have gathered just across the border. Ukraine advances In an interview with The Associated Press on Sunday, rebel spokeswoman Elena Nikitina denounced the government as "incapable of negotiating" and said talks on the conflict could only begin if the Ukrainian army withdrew from the region. That is unlikely, since the Ukrainian government has steadily retaken territory from the insurgents over the last few weeks, ousting them from smaller provincial cities and encircling Donetsk. Commanders said the army has been making steady gains and has virtually encircled the separatists' second-largest stronghold of Luhansk, while rebels have declared a "state of siege" in Donetsk, the largest city they hold. Kyiv security officials said separatist fighters were launching counter-attacks to break a tightening noose around the rebels who seek to set up pro-Russian 'people's republics' in the east of Ukraine. A storm of Donetsk by crack troops appears to have been ruled out: Ukraine has little or no expertise in such missions and it would risk heavy civilian casualties and army losses. A siege is the most likely option, with the possibility of an escape corridor for the separatist fighters in the hope they may flee to Russia. Shelling overnight Conditions were clearly deteriorating in Donetsk, the largest rebel stronghold in eastern Ukraine. AP reporters heard 25 loud explosions in as many minutes around noon on Sunday. More than 10 residential buildings, as well as a hospital and a shop, were heavily damaged by shelling overnight, and several buses caught in the crossfire were still burning Sunday morning. Donetsk city council spokesman Maxim Rovinsky told AP Saturday that over 2,000 residential buildings have been damaged by shelling. At least 300,000 of Donetsk's 1 million residents have fled as violence escalates between Ukrainian government forces and pro-Russian separatists, claiming the lives of over 1,300 people since April, according to the United Nations.
