Almost a month after the start of the conflict, this map shows the advance of Russia in Ukraine

Why have the Minsk agreements not worked? 2:04 (CNN Spanish) — Almost a month ago, Russian troops crossed the border to invade Ukraine and, since then, have continued their attack from the north, east and south. But the speed of the offensive has slowed down, and the main cities, including Kyiv, the capital, remain in Ukrainian hands.

Ukrainian forces said a counterattack north and west of Kyiv appears to have made some progress and that they have regained control of Makariv, a city west of the capital. Meanwhile, the war continues in Mariupol, in the southeast, where satellite images show more fires and destruction in the city besieged by the Russian army.
