Patna: With an intense cold wave claiming 30 lives in Bihar so far, authorities in the state capital on Monday extended closure of all public and private schools till Tuesday.

"The Patna district administration has ordered to close all schools till Tuesday to provide relief to children from the intense cold," officials said here.
