Suspected Al-Qaeda gunmen on motorbikes killed a police officer in a drive-by shooting on Sunday in the central province of Baida, Yemen's defence ministry and official Saba news agency reported.
"Captain Adel Wali al-Nahmi, the police chief of Dhi Naem, was assassinated and his bodyguard Adnan al-Qobati wounded in an ambush by Al-Qaeda members," the defence ministry said in a statement on its 26sep.net website.
Saba, quoting security sources in Baida, said the gunmen were on four motorcycles and fled after opening fire on the officer's convoy,
Police and army officers come under frequent attack, with authorities blaming Al-Qaeda for the assaults.
In a bid to clamp down on an increasing number of attacks using motorbikes, authorities earlier this year launched a campaign ordering unlicenced bikes off the streets.
Al-Qaeda took advantage of the weakness of Yemen's central government during a 2011 uprising against now-ousted president Ali Abdullah Saleh to seize large swathes of territory across south and east Yemen.
