Ukraine's counter-offensive slower than expected, but too soon to judge - Pentagon

Ukraine's counter-offensive against Russian forces is going more slowly than expected, a senior Pentagon official said on Friday.

"It's too early to judge how the counter-offensive is going one way or the other because we're at the beginning of the middle," Colin Kahl, the under secretary of defense for policy, told reporters.

"They are still probing Russian lines (and) Russian areas for weak spots," Kahl said.
