Vladimir Putin's army has been spotted moving in defensive reinforced concrete pillboxes - which is being seen as evidence Russia has "run out of strength to attack".
A picture shows a column of military trucks delivering the readymade blockhouses to invaded areas in Ukraine from Russia.
The move comes as Putin’s forces are staging an “operational pause” while also suffering devastating losses in recent days in the occupied Kherson region.
Pro-Ukrainian journalist Ivan Yakovina posted on Facebook the picture of “ready-made reinforced concrete pillboxes brought to Ukraine from Russia."
He said this means that Putin has run out of strength to attack.
Yakovina continued: "He's going to dig in. I am sure that soon Moscow will be shouting about peace and the desire to ‘stop the terrible war that the West started’.
“At the same time, Ukraine will be accused of bloodthirsty madness and senseless aggression.
“I can directly hear these cries of TV propagandists and see these articles of Putin's supporters in the West: ‘It's time to force Zelensky to start negotiations’, ‘Russia wants only peace’, ‘Kyiv insists on continuing the senseless massacre’ and all that stuff.”
He said that to prevent this the West must immediately increase the volume of arms supplies to Ukraine.
The identities of two more colonels killed in the war emerged today.
