KYIV, Jan 26 - Russian missiles and drones hammered two Ukrainian cities overnight, officials said on Tuesday, killing at least two and wounding 23 in the Black Sea hub of Odesa and knocking out power in much of Kharkiv, Ukraine's second-largest city.

The separate attacks were the latest in Moscow's winter campaign of air strikes on Ukrainian energy infrastructure, with Kyiv under pressure to agree to a U.S.-backed peace deal to end the nearly four-year war.
