Pakistan's Prime Minister Imran Khan asks for proof of his country's link to the car bomb attack in Jammu and Kashmir's Pulwama that killed 40 CRPF soldiers. He said that if India struck back, Pakistan will retaliate. India said Pakistan is giving "lame excuses" as Jaish-e-Mohammed chief Masood Azhar is living in Pakistan and that's proof enough for them to act. India has said it is the same old denial by Pakistan.
