Al-Qaida's second-in-command slams US President Barack Obama as a criminal who turns a blind eye to the expansion of Israeli settlements, in an audio tape broadcast by Al-Jazeera news channel on Monday.
"Have we realised the truth of Obama the criminal, or do we still need more crimes to be carried out in Kabul, Baghdad, Mogadishu and Gaza to be sure of his criminality?" Ayman al-Zawahiri asked.
"Have we realised the lowliness of America under the leadership of the smiling and wooing Obama?" he asked in the recording which could not be independently authenticated.
Zawahiri accused the US president of showing little interest in curbing the growth of Israeli settlements in the occupied West Bank, while at the same time forcing Arab leaders to make further concessions to Israel.
"Obama leaves the settlements spread in the West Bank and around Jerusalem, showing little remorse, while he presses the surrendering (Arab) rulers to give in further," he charged.
Egypt-born Zawahiri, the right-hand man of Al-Qaida chief Osama bin Laden, was speaking in a recording released to praise the former leader of Pakistan's Taliban who was apparently killed in a US attack in August.
Zawahiri eulogised Baitullah Mehsud in the 28-minute statement, reported IntelCenter, a US-based group that monitors Islamist websites.
US and Pakistani officials said that Mehsud had most probably died after a missile attack by an American drone in August.
