Shiv Sena (UBT) criticised BJP over its Tiranga Yatra to mark the success of India's Operation Sindoor and said the country's revenge against Pakistan remains unfinished. "India did not teach Pakistan a lesson. Instead it surrendered before (US President) Donald Trump," an editorial in Sena (UBT) mouthpiece 'Saamana' said. India and Pakistan had agreed to immediate ceasefire on May 10.
