Sajid Javid says the attack on the maternity hospital at Mariupol was a "war crime".
He told Sky: "It's an appalling atrocity, it's a war crime.
"Under international law you cannot attack health facilities, hospitals. The most recent information I have from the World Health Organisation is they now have documented evidence of at least 31 such attacks on health facilities, hospitals, including shelling a couple of days ago, a cancer hospital as well."
More than 2,500 residents of the Black Sea port city of Mariupol have been killed since Russian invaded Ukraine on February 24, presidential adviser Oleksiy Arestovych said in a televised interview on Monday.
He said he was citing figures from the Mariupol city administration, and accused Russian forces of preventing humanitarian aid reaching the encircled city on Sunday.
Russia says it does not target civilians and has baselessly accused Ukraine of deliberately hiding weaponry in civilian locations.
The International Committee of the Red Cross yesterday warned that worst-case scenario awaits the hundreds of thousands of civilians trapped by heavy combat in Mariupol unless the parties reach a concrete humanitarian agreement urgently.
“We call on all parties involved in the fighting to place humanitarian imperatives first. People in Mariupol have endured a weeks-long life-and-death nightmare.
"This needs to stop now. Their safety and their access to food, water and shelter must be guaranteed,” said Peter Maurer, ICRC’s president.
Hundreds of thousands of the city’s residents are now facing extreme or total shortages of basic necessities like food, water and medicine.
People of all ages are sheltering in unheated basements, risking their lives to make short runs outside for food and water.
Dead bodies, of civilians and combatants, remain trapped under the rubble or lying in the open where they fell.
