SANAA, Yemen—Yemeni military officials say a suspected al-Qaida suicide bomber attacked a funeral service in the city of Jaar in southern Yemen, killing 15 and wounding 25.

The officials say they believe the funeral was targeted on Saturday because it was for a man who had been close to civilian militias that helped the army in its campaign against al-Qaida. The military regained control of Jaar from militants in June after two months of fighting.

Military officials also say five suspected al-Qaida militants were killed on Saturday in a suspected U.S. aerial drone strike on their vehicle in southeastern Hadramawt province.
