The humanitarian situation in Iran continues to worsen as the war enters its sixth week, the UN's humanitarian coordination agency (OCHA) warns, BBC reports. The number of civilian casualties has risen sharply recently, according to the UN agency. From the start of the war until March 30, more than 2,100 civilians were reported to have been killed and 27,900 injured.
"Attacks on critical civilian infrastructure and industrial facilities have affected basic services such as electricity, water and telecommunications, which has also led to increased immediate and long-term environmental and health risks," OCHA wrote in a statement.
During the night, Saudi Arabia and the United Arab Emirates also said they had been under attack, CBS News reports.
