Buildings investigation launched in wake of Iran earthquake

Iranian President Hassan Rouhani has launched an investigation into why government housing built by his predecessor collapsed while others withstood an earthquake near the border with Iraq that killed hundreds of people.

In the Kurdish town of Sarpol-e-Zahab, which was reconstructed in the decades since the 1980s war with Iraq, the outer walls of building complexes tumbled away in the magnitude 7.3 earthquake on Sunday night.
