A Chabad center in Oklahoma City has opened its building as a shelter for those displaced by a tornado that killed at least 91 people.

The center also is collecting supplies for those left homeless by the tornado that tore through an Oklahoma City suburb on Monday afternoon, leaving at least 91 people dead including at least 20 children, and injured hundreds more.

“While we feel the pain of others, we’re very thankful that we’re able to respond – to use all our energy and all our resources to let the community know we’re here to help,” co-director Rabbi Ovadia Goldman told Chabad.org.

Goldman said that he has received calls from individuals and organizations in New York, Ohio, Iowa, Illinois, California and abroad with offers to help with relief efforts.

Israel’s Prime Minister Benjamin Netanyahu on Tuesday morning sent a letter of condolence to President Obama in the wake of the tornado.

“On behalf of the Government and people of Israel, I offer our heartfelt condolences to you and to the people of the United States on the massive tornado that struck in Oklahoma and exacted such a horrific toll in human life,” read the letter from Netanyahu. “Our thoughts and prayers are with the victims of this tragedy and their families at this difficult time.”
