Meanwhile, Qatari Prime Minister Hamad bin Jassim, who heads the Arab League committee on Syria, said the monitor mission had "made some mistakes," but ruled out pulling them out.

No comment was immediately available from Qatari officials on Sheikh Hamad's remarks, which were reported by KUNA, the Kuwaiti state news agency.
In Damascus, the government announced it had released more than 500 prisoners detained in recent protests. This after some 700 were released last month. The opposition says some 10,000 are still being detained.
