Iran state TV says Israeli strike killed nuclear scientist

Iranian state television said Tuesday an overnight Israeli strike killed a nuclear scientist in northern Iran, before US President Donald Trump said a ceasefire was taking effect between the Middle Eastern foes.

Citing sources, the broadcaster reported the killing of Mohammad Reza Seddighi Saber at his parents' residence in Astaneh-ye Ashrafiyeh in northern Iran.

Mohammad Reza Seddighi Saber was under US sanctions. Several days ago, his 17-year-old son was reported killed in a strike on their home in Tehran, the broadcaster said.
