KYIV, June 29 (Reuters) - Ukraine has arrested a man suspected of committing treason by helping Russia carry out a missile strike on a busy restaurant that killed 12 people in the eastern city of Kramatorsk. Local officials said 12 people were killed and 60 hurt when a Russian missile slammed into the restaurant on Tuesday evening, reducing it to rubble. "Anyone who helps Russian terrorists destroy lives deserves the maximum punishment," President Volodymyr Zelenskiy said in his nightly video message on Wednesday. Asked about the attack on Kramatorsk, the Kremlin said on Wednesday that Russia attacked only military targets, not civilian ones. Kramatorsk lies west of front lines in Donetsk province and would be a likely objective in any westward advance by Russia.
