DUSHANBE, June 15, 2016, Asia-Plus -- Tensions remained high at the border between Afghanistan and Pakistan as a Pakistani army officer wounded in cross-border clashes died on June 14.

Pakistani Prime Minister Nawaz Sharif''s office and the Pakistani military''s press wing also confirmed Changezi''s death.

One Afghan soldier was killed, Afghan officials had said on Monday, according to Reuters .

Meanwhile Associated Press ( AP ) reported today that an Afghan official says renewed clashes at a Pakistan-Afghan border crossing have killed an Afghan border guard and wounded five others.

Pakistan said Wednesday it has dispatched more troops and weapons to the volatile border amid an escalation in tension between the two neighbors.

The Afghan guard is the third fatality since Sunday night, when clashes erupted at the Torkham border crossing over the construction of a gate by Pakistan on allegedly disputed territory.

According to AP , Afghan border police official Jamal Khan says the guard was killed late Tuesday.

Pakistani security officials confirmed the latest exchange of fire but say the cease-fire is now holding.
