A Kabul University professor was killed when a bomb hit his car in Kabul on Thursday, police officials said, the first attack in days after a series of such incidents in recent weeks.

Mubasher Muslimyar, an Islamic law professor, was killed in Kabul along with another person, a police spokesman said. The identity of the second individual killed was not immediately known.

Kabul has seen a series of attacks with small magnetic bombs attached under vehicles and other targeted killings against members of security forces, judges, government officials, activists and journalists in recent weeks.
