Two Pakistani nationals were killed by BSF fire on October 2 in the Ferozepur sector of Punjab along the International Border. Here is what we know so far about the incident that set off a diplomatic row.

India says three individuals entered its territory and kept moving towards the border fence despite repeated BSF warnings. One turned back to Pakistan; the other two were engaged after being assessed as an imminent security threat, the MEA said.

What is confirmed: both countries summoned each other’s diplomats on October 3. India summoned Pakistan’s Charge d’Affaires Saad Warraich; Pakistan summoned India’s Charge d’Affaires in Islamabad.

What is disputed: the identity and intent of the two men killed. India calls them suspected infiltrators and links the incident to armed narcotics syndicates; Pakistan calls them unarmed civilians and demands an independent investigation.

What happens next: the competing accounts will be tested as more details emerge. Watch for official statements from both capitals and whether the row affects the broader relationship.
