Two suspected suicide bombers have died in an explosion outside an intelligence building in the southern Yemeni city of Aden, according to the country's defence ministry, Al-Jazeera reported.
The men killed in Friday's blast in the al-Mansoura district were suspected of having links to al Qaeda, the defence ministry said on its website.
"Two suicide bombers belonging to the Al-Qaeda terrorist network were killed when their motorbike exploded... early on Friday in al-Mansoura," it said, adding that the intended target of the attack was a branch of the political security services.
"The bomb-laden motorbike exploded with the two suicide bombers whose bodies were left in pieces before they managed to carry out their suicide attack that targetted a branch of the political security services in Mansura," the website quoted a security official as saying.
No other casualties were reported.
Al-Qaeda links questioned
Security services had identified one of the two men as Fawaz al-Subaihi, who lived in the neighbourhood where the attack took place.
An on-going investigation is currently working to identify the body of the second attacker, which was said to have been left in pieces.
A witness, speaking to the AFP news agency, said Subaihi owned an area shop and "has no links to Al-Qaeda".
The witness, who identified Subaihi by his remains, said the body of the second attacker had been "torn to pieces".
The deaths come a day after the interior ministry said government troops had killed more than 100 al Qaeda linked fighters in the past two days of an offensive against hideouts in the south.
