A near-total internet blackout continued across Iran on Sunday morning, marking the second day of escalating conflict involving the US and Israel, AP wrote. Monitoring groups reported that connectivity remained severely restricted nationwide. 

Internet watchdog NetBlocks said online access had flatlined at just 1 percent of normal levels. The disruption has left millions unable to communicate or access information as tensions continue to rise, according to AP.

Authorities in Iran have frequently imposed internet and international call restrictions since nationwide anti-government protests began earlier this year. The latest blackout adds to concerns over transparency and access to information during the unfolding crisis.
