Russian drone hits Kyiv security service headquarters, Ukraine vows retaliation

A Russian drone struck the headquarters of Ukraine's SBU security service in central Kyiv on Friday, causing injuries and prompting President Volodymyr Zelenskyy to vow retaliation. Thick smoke rose over the historic district near St. Sophia Cathedral as emergency crews responded. Kyiv Mayor Vitali Klitschko reported five people wounded, and a nearby bakery was destroyed. Zelenskyy said he ordered a "tangible" response matching the attack, noting the drone targeted the SBU chief's office directly. Kyiv has faced ten consecutive days of drone attacks, including a Wednesday strike on a university that injured seven. Direct hits on government buildings are rare in the four-and-a-half-year war, though the SBU has conducted significant operations inside Russia.
