Heraldo de Madrid - India and Pakistan trade fire after deadly escalation

Pakistani Prime Minister Shehbaz Sharif has said that Islamabad would retaliate after India launched deadly missile strikes on Wednesday morning, with days of repeated gunfire along their border escalating into artillery shelling.

"We will avenge each drop of the blood of these martyrs," Sharif said, in an address to the nation.

India said it had destroyed nine "terrorist camps" in Pakistan in "focused, measured and non-escalatory" strikes, two weeks after New Delhi blamed Islamabad for backing an attack on tourists in the Indian-administered side of disputed Kashmir -- a charge Pakistan denies.

At least 43 deaths have been reported from both sides of the border following Wednesday's violence, including children from both nations.

Islamabad said 31 civilians were killed by the Indian strikes and firing along the border, and New Delhi said there were at least 12 dead from Pakistani shelling.

Pakistan's military also said five Indian jets had been downed across the border, but New Delhi has not responded to the claims.

An Indian senior security source, who asked not to be named, said three of its fighter jets had crashed on home territory.

- 'Screamed' -

The largest Indian strike was on an Islamic seminary near the Punjabi city of Bahawalpur, killing 13 people according to the Pakistan military.

Madasar Choudhary, 29, described how his sister saw two children killed in Poonch, on the Indian side of the frontier on Wednesday.

"She saw two children running out of her neighbour's house and screamed for them to get back inside," Choudhary said, narrating her account because she was too shocked to speak.

"But shrapnel got to the children -- and they eventually died."

Muhammad Salman described "panic among everyone" when Indian strikes hit Muzaffarabad, the main city of Pakistan-administered Kashmir, including a mosque.

On Wednesday night, Pakistan military spokesman Ahmed Sharif Chaudhry reported firing across the Line of Control -- the de facto border in Kashmir -- and said that the armed forces had been authorised to "respond in self-defence" at a "time, place and manner of its choosing".

India's army on Thursday morning reported firing "small arms and artillery guns" in multiple sites overnight, adding that its soldiers had "responded proportionately", without giving further details.

India and Pakistan have fought multiple times since the violent end of British rule in 1947, when colonial officers drew straight-line borders on maps to partition the nations, dividing communities.

Muslim-majority Kashmir -- claimed by both India and Pakistan -- has been a repeated flashpoint.

- 'No pushover' -

India's Defence Minister Rajnath Singh said the operation was New Delhi's "right to respond" following an attack on tourists in Pahalgam in Kashmir last month, when gunmen killed 26 people, mainly Hindu men.

New Delhi blamed the Pakistan-based group Lashkar-e-Taiba -- a UN-designated terrorist organisation, and the nations traded days of threats and diplomatic measures.

India on Thursday braced for Pakistan's threatened retaliation.

"Border districts on high alert," The Hindu newspaper headline read, adding that "India must be prepared for escalatory action" by Pakistan.

In an editorial, the Indian Express wrote "there is no reason to believe that the Pakistan Army has been chastened by the Indian airstrikes", adding that Indian military experts were "aware that Pakistan's armed forces are no pushover".

Diplomats and world leaders have pressured both countries to step back from the brink.

"I want to see them stop," US President Donald Trump said Wednesday.

Iranian Foreign Minister Abbas Araghchi is slated to meet his Indian counterpart Subrahmanyam Jaishankar on Thursday in New Delhi, days after visiting Pakistan, as Tehran seeks to mediate.

Analysts said they were fully expecting Pakistani military action to "save face" in a response to India.

"India's limited objectives are met," said Happymon Jacob, director of the New Delhi-based think tank Council for Strategic and Defence Research.

"Pakistan has a limited objective of ensuring that it carries out a retaliatory strike to save face domestically and internationally. So, that is likely to happen."

Jacob suggested that, based on past conflicts, he believed it would "likely end in a few iterations of exchange of long-range gunfire or missiles into each other's territory".
