Al-Qaeda's wing in Yemen has said it carried out separate attacks on a French oil pipeline and a Chinese oilfield last week in Yemen, web monitoring group SITE said on Monday.

The attackers, calling themselves the Jund Al-Yemen Brigades claimed they detonated a timed explosive Thursday on a pipeline belonging to France's Total in the western Saah district, the SITE Intelligence Group reported.

In a statement posted on an Islamist militant website, the group also said it fired mortars Saturday at an oilfield owned by an unidentified Chinese firm in the eastern district of Hadramut.

"Both these operations are stated as means of support against the enemy," SITE reported, adding that the authenticity of the message could not be verified.

There were no previous reports of the alleged attacks.

In a similar statement on the Internet last week, the militant group said it had targeted the US embassy in Sanaa in an attack that hit a nearby school in the Yemeni capital, without giving the date of the March 18 attack.

A schoolgirl and a policeman were killed and 19 other people wounded in the attack, which Washington said had targeted the US embassy.

The Jund al-Yemen Brigades has claimed responsibility for previous attacks on Belgian and Spanish tourists in Yemen.

Yemen, one of the world's poorest countries, is awash with weapons and is the ancestral homeland of Al-Qaeda leader Osama bin Laden.

Al-Qaeda claimed responsibility for a suicide attack in October 2000 that killed 17 US sailors on the destroyer USS Cole in the southern Yemeni port of Aden.
