Warsaw: The United States will "adapt as necessary” its military support for Ukraine, Secretary of State Antony Blinken said on Thursday, offering another hint that the Biden administration could soon lift its restrictions on Kiev’s use of long-range weapons.

Blinken, who was visiting Poland a day after talks with Ukrainian President Volodymyr Zelensky in Kiev, was asked at a press conference whether Washington had given Ukraine the green light to attack targets inside Russia with Western weapons.

"At every step along the way, as necessary, we’ve adapted and we’ve adjusted,” Blinken replied.

"One of the purposes of my visit to Kiev yesterday was to hear from our Ukrainian partners what they believe they need now to deal with the current battlefield, including in eastern Ukraine and other parts of the country.”

"I can tell you that as we go forward we will do exactly what we have already done, which is we will adjust, we’ll adapt as necessary - including with regard to the means that are at Ukraine’s disposal.”

Blinken’s Polish counterpart, Radostaw Sikorski, called on Western allies to "continue to equip Ukraine with advanced air and missile defence systems and to lift restrictions on the use of long-range weapons.” (DPA)
