President Donald Trump is weighing up sending long-range Tomahawk cruise missiles to Ukraine, a move that Russian President Vladimir Putin has warned would destroy Washington's relations with Moscow but could make a real difference to Ukraine's war effort—and send a strong political signal to the Kremlin.

The Kremlin will only negotiate if missiles and drones bring the pain of war home to Russians, Ukrainian officials say.

Russian forces attacked Kharkiv, Ukraine's second-largest city, with guided bombs on Monday, knocking out power to 30,000 customers in three districts, local officials said.

Russian drone and missile strikes caused blackouts across large swaths of Ukraine, damaged residential buildings and injured at least 20 people in Kyiv, authorities said.

Russia carried out a “massive attack” on Ukraine’s energy infrastructure, top Ukrainian officials said early Friday, leaving parts of the capital Kyiv without power.

Power has been restored to over 800,000 residents in Kyiv, a day after Russia launched major attacks on Ukraine's power grid, causing widespread blackouts.

YG then called in artillery strikes. We watched as the first one struck about 20 yards from the trees where the Russians were hiding. The second landed on the opposite side but almost as far away, leaving a visible crater in the earth. It was time to send in an assault team.

A West Yorkshire councillor has described the "unnerving and unsettling" experience of surviving a missile attack while on a humanitarian aid mission to Ukraine. John Lawson was caught up in a Russian drone attack when he travelled to Lviv as part of a convoy to deliver emergency supplies last month.
