Sri Lanka, March 5 -- Iran's internet blackout has now passed 120 hours, with connectivity in the country flatlining at around 1% of its typical levels, according to independent watchdog organization NetBlocks.

Netblocks added that Iranian telecommunications companies are engaging in "Orwellian" behavior, threatening legal action against users attempting to access the global internet.

The move has made it difficult to obtain a full picture of what's happening within Iran.

Meanwhile, explosions rocked Tehran again this morning leaving more residents unsure whether to leave or stay put, a man who fled the city told CNN.

Loud bangs were heard in the Iranian capital Thursday morning, the semi-official state news agency Tasnim reported.
