Karachi authorities placed the city on high alert between 6:46 PM and 7:15 PM UTC on February 23, 2026, following intelligence reports indicating possible terror threats from militant groups in response to Pakistan's recent airstrikes in Afghanistan's Nangarhar province, according to ARY News citing law enforcement sources shared by MCIAZayyan on X. The alert prompted heightened security measures across Karachi, Pakistan's largest city, as officials responded to credible intelligence on potential attacks by terror groups, per the ARY News report posted during the 29-minute reporting window. This development occurs amid escalating border tensions after Pakistani airstrikes in Nangarhar earlier on February 23, 2026, as covered in prior reports. Pakistan's strikes targeted Tehrik-i-Taliban Pakistan (TTP) positions, prompting warnings of further action from Afghan soil, according to Khyber Pakhtunkhwa Governor Faisal Karim Kundi as reported by PakTVGlobal. Russian Foreign Ministry estimates of up to 23,000 militants in Afghanistan, including 5,000-7,000 TTP fighters, were rejected by Taliban spokesperson Zabihullah Mujahid earlier today, per Khorasan Diary on X.
