Blasts rock Kyiv during UN chief's visit, US pledges new aid

Russia fired two missiles into Kyiv on Thursday during a visit by UN Secretary General Antonio Guterres, Ukrainian officials said, as Moscow pressed an assault in the east that drew new US pledges of military and humanitarian aid.

The rockets shook the central Shevchenko district in Ukraine's capital and one of them struck the lower floors of a 25-storey residential building, injuring at least 10 people, Ukrainian officials said.
