Bangladesh Army deployed massive security across Dhaka Airport, Dhaka University, and other critical locations in Dhaka on December 19, 2025, between 11:16 a.m. and 11:46 a.m. UTC, as the mortal remains of youth leader Osman Hadi prepare to return from Singapore shortly, according to Aditya Raj Kaul on X. The deployment comes amid ongoing nationwide unrest following Hadi's death, with previous protests in Dhaka featuring anti-India slogans earlier this morning, as reported by Goreunit on X. Former Indian High Commissioner to Bangladesh Pinak Ranjan Chakravarty stated there is credible evidence of Pakistan's ISI exploiting the unrest to fuel anti-India sentiment through links with Jamaat-e-Islami, according to PTI_News on X within this period. Security measures in Dhaka build on earlier incidents, including an Islamist mob storming Awami League organising secretary Mohibul Hasan Chowdhury Nowfel's residence in Chattogram between 9:16 a.m. and 9:45 a.m. UTC and increased security outside the Bangladesh High Commission in Delhi from 10:46 a.m. to 11:16 a.m. UTC, as cited by Aditya Raj Kaul and WIONews via sidhant on X. In a separate development, U.S. Embassy Marines and Bangladesh military personnel participated in a Marine Corps Combat Fitness Test at Bangladesh Army Stadium, according to the U.S. Embassy Dhaka on X.
