Fighting in Ukraine continues overnight ahead of crucial diplomatic push

Fighting is continuing to rage in eastern Ukraine ahead of crucial peace talks later in the day.

Shelling early Wednesday rocked a bus station in the rebel stronghold of Donetsk, where an Associated Press reporter saw one body at a bus station and was told by rebel officials that another body had been recently removed from the scene. Donetsk city officials said in a statement that three people had been killed overnight.

Ukrainian President Petro Poroshenko posted a statement on his website saying that he had made an impromptu visit to the war-torn region early Wednesday.

"We demand an unconditional peace," Poroshenko said. "We demand a cease-fire, a withdrawal of all foreign troops, and closing of the border. ... We will find a compromise within the country."
