On the ground: Russian drone strikes Ukraine security service headquarters in Kyiv

A Russian drone struck the headquarters of Ukraine's SBU security services on Friday, Ukrainian President Volodymyr Zelensky said, accusing Moscow of aiming directly at the SBU head's personal office. Zelensky said he had instructed the SBU to deliver an "appropriate, tangible response" to the strike, while Ukraine's Foreign Minister Andriy Sybiga described it as a "major escalation".
