Thousands throng the streets of Iran's capital Tehran for the funeral of an assassinated nuclear scientist.
Thirty-two year old Mostafa Ahmadi-Roshan was reportedly killed by a motorbike hitman who put a magnetic bomb on his car on a busy street on Wednesday.
Iranian television broadcast the funeral as the country blamed Israeli and US agents for the killing - but said it would not derail its nuclear programme .
It is the fifth daylight attack on technical experts involved in Iran's nuclear program in two years.
The United States has denied involvement in the bomb which also killed Ahmadi-Roshan's driver.
