The extremist network also denied reports confirmed by Yemen's President Abdrabuh Mansur Hadi that US intelligence services had intercepted a conversation between Al-Qaeda chief Ayman al-Zawahiri and Nasser al-Wuhayshi, head of the Yemen-based Al-Qaeda in the Arabian Peninsula.

"Hadi repeated the nonsense and propaganda published by US intelligence on telephone calls between jihadist leaders to justify the US plot to kill Muslims in Yemen through continued raids," AQAP said in the statement posted on jihadist Internet forums.

Hadi had "claimed the jihadists were plotting to target oil terminals in the country using bomb-laden trucks," said AQAP.

"We deny what he said and regard it as an attempt to justify US criminal practises.

"We also affirm our concern... in preserving the blood of Muslims," the statement added.

A source close to Hadi quoted the Yemeni leader as saying Friday that in the alleged conversation between the Al-Qaeda leaders Wuhayshi told Zawahiri he would be hearing of something "that will change the course of history".

Hadi and US President Barack Obama had discussed the matter at the White House on August 1, according to the same source.

On August 4, the United States shut 19 of its consulates and embassies in the Arab and Muslim countries amid what American officials said was a threat of an imminent Al-Qaeda attack.

The missions were later reopened.
