KYIV, Aug 21 - Fighting in southern Ukrainian areas just north of Crimea has stepped up in recent weeks as Ukrainian forces try to drive Russian forces out of cities they have occupied since early in the six-month-old war, The Associated Press reported.

A Russian missile attack wounded 12 people, including three children, and damaged houses and an apartment block Saturday in the town of Voznesensk in the Mykolaiv region, the Ukrainian prosecutor’s office said. Two of the children were in serious condition and the governor said one had lost an eye.

A Ukrainian airstrike, meanwhile, hit targets in Melitopol, the largest Russian-controlled city in the Zaporizhzhia region, 100 kilometers north of Crimea, according to Ukrainian and Russia-installed local officials.

The Ukrainian military on Saturday said it had destroyed a prized Russian radar system and other equipment stationed in occupied areas in the southern Zaporizhzhia region. It was not clear if this was the strike on Melitopol.

“Tonight, there were powerful explosions in Melitopol, which the whole city heard,” the Ukrainian mayor of Melitopol, Ivan Ferodov, said. “According to preliminary data, (it was) a precise hit on one of the Russian military bases, which the Russian fascists are trying to restore for the umpteenth time in the airfield area.”

In the east, Ukraine’s military General Staff said Saturday that intensified combat took place around Bakhmut, a small city whose capture would enable Russia to threaten the two largest remaining Ukrainian-held cities in the eastern Donbas region.

Bakhmut for weeks has been a key target of Moscow’s eastern offensive as the Russian military tries to complete a months-long campaign to conquer all of the Donbas, where pro-Moscow separatists have proclaimed two republics that Russia recognized as sovereign states at the beginning of the war.

A local Ukrainian official reported sustained fighting Saturday near four settlements on the border of Luhansk and Donetsk provinces, which together make up the contested Donbas region. Luhansk Gov. Serhii Haidai did not name the settlements. Russian forces overran nearly all of Luhansk last month and since then have focused on capturing Ukrainian-held areas of Donetsk.

Russian shelling killed seven civilians Friday in Donetsk province, including four in Bakhmut, Gov. Pavlo Kyrylenko wrote Saturday on Telegram. Taking Bakhmut would give the Russians room to advance on the province’s main Ukrainian-held cities, Kramatorsk and Sloviansk.

Ukraine said Sloviansk and Kramatorsk were targeted Friday, along with the Kharkiv region to the north, home to Ukraine’s second-largest city. (ap/ez)
