Ukrainian President Volodymyr Zelenskyy said on Thursday that technical details still need to be agreed with the United States before Patriot air-defence missile production can begin in Ukraine.

US President Donald Trump said on Wednesday that he would allow Kyiv to manufacture them.

"And now, after our agreement with the president, our teams...must agree on all the remaining technical aspects," said Zelenskyy, answering a question on the Patriot system during a WhatsApp briefing with journalists.

"We are working with our European partners to obtain additional missiles, as we do not yet have our own system, of course."

Speaking alongside Zelenskyy at the NATO summit in Ankara on Wednesday, US President Donald Trump said Washington would give Kyiv “the right to make Patriots,” the long‑range air defence missiles Kyiv has repeatedly requested to protect its cities and energy grid from Russian strikes.
