The news article is from the year 2000. All of the peaks except pt 5353 were vacated by Pakistan after 2003 agreement.
Only pt. 5353 remains under pakistani occupation. India was not able to take back pt.5353 as the approach was relatively difficult from indian side when compared to pakistani side. Also Pakistan army had vacated pt.5353 after Kargil war was over. Both the side had agreed to maintain pt.5353, 5240, 4251 and 4875 as no man's land. Few months later pakistan occupied pt.5353, built concrete bunkers and a motorable road connecting pt. 5353 to Benazir post. Pt. 5240 and pt.5310 were occupied by Indian Army 16 Grenediers and 14 Sikh respectively in the year 2000. 1/3 Gurkha Rifles was tasked with occupying pt.5353 but they never made it as the approach from indian side was nearly vertical and pakistani posts present on either side of the approach directed effective fire on the troops assaulting the position. 1/3 Gorkha returned with 19 casualties and it was decided not to take back pt.5353. Using air power was out of question as the Kargil war was over a year before pakistan occupied pt.5353.
June 1999: Indian Army under Brig. P. C. Katoch, Col. Konsam Himalaya Singh seized control of pt 5770 (Naveed Top/Cheema Top/Bilal Top) in southern edge of the Saltoro defense line In Siachen from Pakistan troops.

In the Year 2002 Indian soldiers on three posts, namely Point 5165, Point 5240 and Point 5100, guided their superior 155-millimetre Bofors howitzers with devastating accuracy. Pakistani troops on Point 5353 were first hit with smoke-filled mortar shells, to flush them out of their bunkers, and then with air-burst artillery, which showered down shards of metal at great speed. Well over 40 Pakistanis are believed to have died on Point 5353. Pakistan could not reinforce the troops since the Indian soldiers on Point 5165 and Point 5240 were in a position to hit their supply lines.
