The Israeli military on Sunday reported attacks on Tehran and other targets aimed at Iranian infrastructure and power structures.

Iran's Fars news agency, which is linked to the Islamic Revolutionary Guard Corps (IRGC), reported missiles striking a residential area to the south of Tehran. Ten people had died in the attack, including six Afghan migrants, Fars said.

The US-based Human Rights Activists in Iran (HRANA) reported on Saturday that the attacks on Iran over recent days had been the heaviest since the current war began on February 28. HRANA said that 74% of the attacks had targeted the Tehran region.

The organization put the casualty toll thus far at 3,400 killed, including at least 1,500 civilians.

Iranian forces continued attacks on Israel. Air raid sirens were heard in cities in the south of the country. Israel's Magen David Adom emergency medical service said there were no reports of injury. Iranian media confirmed the attacks.

Israeli media reported the attacks had targeted Dimona in the Negev desert, where Israel's nuclear reactor is located.

An attack a week ago caused dozens of injuries and destruction to a residential area.
