Blinken lands in Kyiv amid Ukraine push for long-range missile strike permission

LONDON -- Secretary of State Antony Blinken arrived in Kyiv on Wednesday morning as Ukrainian leaders pressed for U.S. permission to use American-made long-range weapons against targets inside Russia.

America's top diplomat was accompanied by British Foreign Secretary David Lammy. The pair are scheduled to meet with Ukrainian President Volodymyr Zelenskyy and "senior Ukrainian government officials," according to a State Department statement.

Blinken will "discuss continued support for Ukraine's defense against Russia's aggression and how to ensure Ukraine can thrive militarily, economically, and democratically in the long term," it added.

Restrictions on Ukraine's use of American long-range weapons is one of the most pressing issues for Blinken during the visit.

Kyiv has long been advocating for U.S. permission to strike military targets within Russian borders, including airfields that are key to Moscow's long-range missile campaign against Ukrainian cities.

"We continue to persuade our partners at all levels about long-range capabilities," Zelenskyy wrote on his Telegram channel on Sunday.

"Russia can avoid seeking peace only as much as the world avoids making strong decisions aimed at Russia's defeat. Long-range capabilities are one of those key, strategic decisions."

Yehor Cherniev -- a member of the Ukrainian parliament and the chairman of his country's delegation to the NATO Parliamentary Assembly -- told ABC News Ukrainians are hoping for U.S. permission to use the MGM-140 Army Tactical Missile System, colloquially known as the ATACMS, for strikes within Russia. The longest-range variant of the weapon can hit targets out to 190 miles.

"It will inspire Ukrainians and our army," Cherniev said. Russian airfields and military depots will be top of Kyiv's target list if American restrictions on ATACMS use are indeed lifted, he added.

Kremlin spokesperson Dmitry Peskov told journalists at a Wednesday briefing that he expects the U.S. to give its permission.

"Most likely, of course, all these decisions have already been made," he said, as quoted by the state-run Tass agency.

Blinken is scheduled to hold a press conference at 12 p.m. ET.
