India-Pak conflict Tensions between the neighbouring countries have skyrocketed since the April 22 attack wherein 26 people, most of them tourists from across India, were gunned down by terrorists. After a flurry of diplomatic actions, India launched coordinated missile strikes on terror bases in Pakistan and Pakistan-occupied Kashmir earlier this week, with Defence Minister Rajnath Singh saying that 100 terrorists were killed in the attack. The Pakistani Army also attempted several missile strikes on India and resorted to ceasefire violations across the Line of Control. New Delhi says the attack in Pahalgam was planned and executed by terrorists associated with groups based out of Pakistan. (With inputs from news agency PTI).
