Tetiana Stawnychy, the president of Caritas Ukraine, a Catholic charity, expressed concern that Ukraine is heading for a humanitarian catastrophe, adding that there were already 2.9 million people on both sides of the contact line who were in need of humanitarian assistance before the attack.
"The events which began early this morning will inevitably lead to a colossal humanitarian catastrophe," Stawnychy said.
"It is impossible to believe that in the 21st century in the center of Europe people have to wake up at 5 am from explosions and the sound of air raid sirens," she said.

English Cardinal Vincent Nichols underlined that dialogue and negotiation are the only way forward.
