KHROMOVE, Ukraine >> Pressure from Russian forces mounted Saturday on Ukrainians hunkered down in Bakhmut as residents attempted to flee with help from troops who Western analysts say may be preparing to withdraw from the key eastern stronghold.

A woman was killed and two men were badly wounded by shelling while trying to cross a makeshift bridge out of the city in Donetsk province, according to Ukrainian troops who were assisting them.

A Ukrainian army representative who asked not to be named for operational reasons told The Associated Press that it was now too dangerous for civilians to leave Bakhmut by vehicle and that people had to flee on foot instead.

Bakhmut for months has been a prime target of Moscow’s grinding eastern offensive in the war, with Russian troops, including forces from the private Wagner Group, inching ever closer.

An AP team near Bakhmut on Saturday saw a pontoon bridge set up by Ukrainian soldiers to help the few remaining residents reach the nearby village of Khromove. Later, they saw at least five houses on fire as a result of attacks in Khromove.

Ukrainian units over the past 36 hours destroyed two key bridges just outside Bakhmut, including one linking it to the nearby town of Chasiv Yar along the last remaining Ukrainian resupply route, according to U.K. military intelligence officials and other Western analysts.

The U.K. defense ministry said in the latest of its regular Twitter updates that the destruction of the bridges came as Russian fighters made further inroads into Bakhmut’s northern suburbs.

The Institute for the Study of War, a Washington-based think tank, assessed late Friday that Kyiv’s actions may point to a looming pullout from parts of the city. It said Ukrainian troops may “conduct a limited and controlled withdrawal from particularly difficult sections of eastern Bakhmut,” while seeking to inhibit Russian movement there and limit exit routes.

Capturing Bakhmut would not only give Russian fighters a rare battlefield gain after months of setbacks, but it might rupture Ukraine’s supply lines and allow the Kremlin’s forces to press toward other Ukrainian strongholds in the Donetsk region.

Civilians spoke about daily struggles as the fighting raged on nearly nonstop, reducing much of Bakhmut to rubble.
