Ukraine said more than 30 people are dead and 100 wounded after rockets hit a train station in the city of Kramatorsk in eastern Ukraine. Thousands of people were at the station at the time as they try to flee Russian attacks, according to the Donetsk regional governor. Ukraine's President Volodymyr Zelensky has condemned the attack on the Kramatorsk train station. "Lacking the strength and courage to stand up to us on the battlefield, they are cynically destroying the civilian population. This is an evil that has no limits. And if it is not punished, it will never stop," Zelensky said. Kramatorsk railway station has been a crucial hub for the evacuation of civilians from the Donbas region. Police said first responders are continuing to work at the scene. "It is already known there about 30 dead people, including children, and about 100 injured," the statement read. "Assistance is being provided to all who need it." Eyewitnesses said more than a thousand people were at the railway station when it was attacked. Nathan Mook, CEO of the World Central Kitchen charity, was at the station just moments before the attack and spoke to the BBC about what he witnessed. "We were driving by the station over an overpass, we could see well over a thousand people. It was crowded, just like it was yesterday and the day before," he said. Mook said he then heard the sound of five to 10 explosions "two minutes after we had driven by". "You feel it before you hear it. The explosion rattles you on the inside," he said. "One of our guys at the [food] warehouse said he had seen Ukrainian air defenses intercept one of the rockets. These were missiles." After driving back to the site of the attack, Mook describes a scene of devastation: "The remnants of one of the missiles in the parking lots, blown-out windows, a couple of dozen casualties." "Emergency crews were on the ground very quickly, tending to people that were injured and had been killed," he added. The European Union's high representative for foreign affairs and security policy, Josep Borrell, has strongly condemned a rocket strike on the railway station in the eastern Ukrainian city. "I strongly condemn this morning's indiscriminate attack against a train station in #Kramatorsk by Russia, which killed dozens of people and left many more wounded," Borrell said on his official Twitter account Friday. "This is yet another attempt to close escape routes for those fleeing this unjustified war and cause human suffering." Borrell and European Commission President Ursula von der Leyen will be meeting with Ukrainian President Volodymyr Zelensky in Kyiv on Friday. European Council President Charles Michel also condemned the strike. — Agencies
