Yemeni loyalist forces and onlookers gather at the scene of a suicide attack targeting the police chief in the base of the Saudi-backed government on April 28, 2016 in Yemen's second city Aden. The bombing came after loyalist forces backed by a Saudi-led military coalition seized the key southeastern port city of Mukalla and the nearby airport and oil facilities from Al-Qaeda, ending a year-long occupation by the jihadists. General Shallal Shayae escaped unharmed from the attack but several people were wounded when the bomber blew up a vehicle packed with explosives, a security official said. / AFP / SALEH AL-OBEIDI (Photo credit should read SALEH AL-OBEIDI/AFP/Getty Images)
