Pakistan summoned India's deputy high commissioner for the fourth consecutive day yesterday over the alleged "unprovoked firing" by Indian troops across the Line of Control which resulted in the death of two people.

The tensions have increased between the two sides due to ongoing skirmishes and Pakistan has summoned India's Deputy High Commissioner J P Singh five times since Monday.

Director General (South Asia and SAARC) Mohammad Faisal summoned Singh and "condemned the unprovoked ceasefire violations" by Indian forces, the Foreign Office said.

In a statement, it claimed that the latest violation by Indian forces occurred on January 20-21, when 18 Indian posts resorted to "unprovoked firing" with mortars and heavy weapons in the Nikial sector at the LoC.

The firing killed two civilians - a 33-year-old man and a 25-year-old woman - and injured another women and a girl, the Foreign Office said.

Faisal said the deliberate targeting of civilian populated areas is indeed deplorable and against the human dignity, international human rights and humanitarian laws.

The repeated ceasefire violations by India "are a threat to regional peace and security and may lead to a strategic miscalculation," he asserted.
