A rocket strike by pro-Russian rebels in the eastern Ukrainian region of Luhansk killed at least 23 servicemen and wounded nearly 100 on Friday.
Ukrainian officials said rebels fired a barrage of Grad rockets at troops in Zelenopillya, a village close to the Russian border.
Ukrainian President Petro Poroshenko promised retaliation on his website. “All those who used the Grad against the Armed Forces of Ukraine will be found and destroyed.”
“For every soldier’s life, the militants will pay with scored and hundreds of their own. Not a single terrorist will avoid responsibility; each will get what they deserve,” he said.
The pro-Russian forces launched a volley of Grad missiles at 4:30 a.m. on the border post at Zelenopillya, military sources said.
Ukraine’s Defence Ministry said 19 servicemen were killed, while four border guards were also killed. Military spokesman Vladyslav Seleznyov posted on his Facebook page that 93 were injured in the Grad attack.
