Hundreds of Sudanese troops arrived in Yemen's southern port city of Aden on Saturday as the first batch of 10,000 reinforcement for the Saudi-led coaltion fighting against Iran-backed Shiite Houthi rebels.
According to pro-government officials, the Sudanese troops’ duty will be securing Aden, which has witnessed many drive-by attacks by armed groups on pro-government forces.
On Friday an official and aid worker from United Arab Emirates, another member of the Saudi-led coalition, was assasinated by a gunman on a motorcycle in Aden’s Mansoura neighbourhood.
The UAE's state news agency WAM identified the soldier as Captain Hadef Hameed al-Shamesi. No further details were given.
A Yemeni official told the Associated Press news agency that the aid worker had been killed by an unidentified gunman.
"He was shot dead when he exited the vehicle near a store by gunmen pursuing in another car," said the official.
Officials also said Al Qaeda militants had gained territories and set up security checkpoints in Zinjibar, the provincial capital of Abyan.
"First they took Mukalla and then Zinjibar. We are all worried Aden may be next," one pro-government security official said.
Friendly fire from Saudi-led coalition
According to local officials, Saudi-led coalition jets striking Iran-backed Houthi militias accidentaly bombed and killed 30 Yemeni fighters loyal to Yemeni President Abd-Rabbu Mansour Hadi.
The friendly fire which also left 40 wounded was the latest of the series of friendly fire incidents since the operation started in March.
Officials from Hadi’s administration said Saturday's strikes hit a mountainous area close to the southwestern city of Taiz where fighting is intense between troops and rebels loyal to veteran former president Ali Abdullah Saleh, who has sided with the Houthis.
One official said, "The coalition raid hit the wrong target."
Ground fighting and Saudi-led air strikes have killed at least 5,400 people in Yemen since Saudi Arabia began fighting in Yemen to restore Hadi's government.
Hadi's government has since returned from exile in Saudi Arabia to Aden and settled its government in a temporary headquarters in Aden’s al-Qasr hotel.
