One person was killed and eight injured after two explosive devices went off near a football team's offices in the southern Yemeni port city of Aden on Monday, witnesses and medical sources said, dpa reported.
Witnesses said the explosions occurred at the gate of the al-Wahda football team's offices in a crowded street of the Sheikh Othman area in Aden.
One of nine people rushed to two hospitals in the area died of his injuries, sources at al-Naqib hospital said.
Aden is due to host an Arab Gulf football tournament in November, amid an escalating war with al-Qaeda and a growing separatist movement in the south of the country.
Earlier in the month, Yemeni President Ali Abdullah Saleh said his government would deploy 30,000 soldiers to secure the competition.
The eight-team tournament representing the six Arab Gulf states, in addition to Iraq and Yemen, is scheduled to kick off in Aden on November 22. The competition is due to end on December 5.
