Jammu, Jan. 5 -- The Chinese People's Liberation Army (PLA) escalated the situation in the sensitive Ladakh theatre by using unorthodox weapons against Indian soldiers and amassing a large number of troops during the ongoing border standoff along the contested Line of Actual Control (LAC), the defence ministry said in a year-end review of major developments.

While the ministry did not elaborate on the unorthodox weapons used, the PLA troops attacked Indian soldiers with stones, iron rods and nail-studded clubs during skirmishes in Pangong Tso and the Galwan Valley last year.
