Russian rockets struck the western Ukrainian city of Lviv on Saturday, while President Joe Biden visited neighboring Poland, a reminder that Moscow is willing to strike anywhere in Ukraine despite its claim to be focusing its offensive on the country’s east.

The back-to-back airstrikes shook the city that has become a haven for an estimated 200,000 people who have had to flee their hometowns.

Lviv had been largely spared since the invasion began, although missiles struck an aircraft repair facilitynear the main airport a week ago.

Among the many who sought refuge in Lviv was Olana Ukrainets, a 34-year-old IT worker from the northeastern city of Kharkiv.

“When I came to Lviv, I was sure that all these alarms wouldn’t have any results.

“Sometimes when I heard them at night, I just stayed in bed. Today, I changed my mind and I should hide every time. … None of the Ukrainian cities are safe now,” Ukrainets said from a bomb shelter after the blasts.

The city was home to about 700,000 people before the invasion. Some who no longer feel safe here will head for nearby Poland.

Biden met there Saturday with refugees in a show of solidarity, though he was in the capital, Warsaw, and far from the Ukrainian border, which is about 45 miles (72 kilometers) west of Lviv.

Lviv also has become a humanitarian staging ground for Ukraine, and the attacks could further complicate the already challenging process of sending aid to the rest of the country.

The first strike involved two Russian rockets that hit an industrial area in the northeastern outskirts of Lviv and apparently injured five people, the regional governor, Maksym Kozytskyy, said on Facebook.

A thick, black plume of smoke billowed from the site for hours.

According to AP, a second rocket attack occurred just outside the city hours later and caused three explosions, Kozytskyy told a press briefing as another round of air raid sirens wailed.

He said an oil facility and factory connected to the military, both in areas where people live, were struck Saturday, though he didn’t give more details.

In the dim, crowded bomb shelter under an apartment block a short ways from the first blast site, Ukrainets said she couldn’t believe she had to hide again after fleeing from Kharkiv, one of the most bombarded cities of the war.

“We were on one side of the street and saw it on the other side.

“We saw fire. I said to my friend, ‘What’s this?’ Then we heard the sound of an explosion and glass breaking. We tried to hide between buildings. I don’t know what the target was,” she said.
