Rockets kill dozens in Ukraine port of Mariupol
Dozens of people have been killed or injured in a series of rocket attacks by pro-Russian rebels in Ukraine's government-held port of Mariupol, police there say.
The Grad rockets hit a market in a residential area in the east of the city, the police chief said.
A spokesman for the rebels denied that they had any involvement in the attack, calling it "blatant misinformation".
