(AP) UNITED NATIONS - Secretary-General Ban Ki-moon said Thursday the crisis in Syria is getting worse and claiming more lives every day even though President Bashar Assad's government insists it is withdrawing troops ahead of a U.N. deadline to end the violence.
The U.N. chief appealed to Assad "to show vision and leadership" and keep his pledge to pull troops and heavy weapons out of cities and towns by April 10, and he urged the opposition to be ready to stop all violence if the Syrian government meets the deadline.
"Cities, towns and villages have been turned into war zones. The sources of violence are proliferating," Ban told the U.N. General Assembly. "The human rights of the Syrian people continue to be violated. ... Humanitarian needs are growing dramatically."
His comments came as activists reported that Syrian troops attacked the Damascus suburb of Douma, an assault they said shows that Assad is intensifying violence in the days before the April 10 deadline. His crackdown on the yearlong uprising has left at least 9,000 people dead, according to the U.N.
Earlier Thursday, a U.N. team arrived in Damascus to start technical preparations for the possible deployment of U.N. monitors for any cease-fire between Syrian troops and rebel forces.
Kofi Annan, the U.N.-Arab League envoy trying to end the conflict, said Syria has informed him of partial withdrawals from three locations Idlib, Zabadani and Daraa "but it is clear that more far-reaching action is urgently required."
"We must silence the tanks, helicopters, mortars and guns, and stop all other forms of violence too: sexual abuse, torture, executions, abductions, destruction of homes, forced displacement, and other such abuses, including on children," he said.
Annan and Ban spoke to the General Assembly minutes after the U.N. Security Council called on Syria to "urgently and visibly" fulfill its pledge to halt the use of troops and weapons by April 10. It called on the government and opposition to stop all violence within 48 hours if Syria meets the pullout deadline.
The presidential statement raised the possibility of "further steps" if Syria doesn't implement the six-point peace plan outlined by Annan, which Assad agreed to on March 25.
The statement called on all parties, including the opposition, to stop armed violence in all forms in 48 hours after the Syrian government fully fulfills the measures.
"All points of the plan are crucial, but one is most urgent: the need for a cessation of violence," Annan told diplomats from the 193 U.N. member states by videoconference from Geneva. "Clearly, the violence is still continuing. Alarming levels of casualties and other abuses continue to be reported daily. Military operations in civilian population centers have not stopped."
Ban said despite the Syrian government's acceptance of Annan's plan, "the violence and assaults in civilian areas have not stopped."
"The situation on the ground continues to deteriorate," he said.
The secretary-general has been speaking out against the violence in Syria for many months, but his remarks Thursday were especially strong and highly critical of the Assad government for unleashing attacks in the first place in response to "the legitimate demands of the Syrian people the same demands that people across the Arab world have been making for more than a year now."
Syria's U.N. Ambassador Bashar Ja'afari confirmed that hostilities have escalated in some "hotspots" where he said armed groups have "jumped to fill the vacuum" when they heard that the Syrian government withdrew some military units.
He reiterated the government's commitment to "the success" of Annan's six-point plan and said all heavy weapons would be withdrawn by April 10. But he also appeared to put at least one condition on the pullout of Syrian troops from cities and towns.
Ja'afari accused Qatar, Saudi Arabia, Turkey, France and the United States of assisting the Free Syrian Army and said his government needs "a crystal cut commitment and a guarantee by Mr. Annan himself after he consults with Saudi Arabia, Turkey and the others that once the government will observe and will respect the end of violence, the other parties will do the same and not fill the vacuum."
He said obtaining the guarantee before the April 10 deadline for the pullout "is an integral part of the common understanding between Mr. Kofi Annan and the Syrian government." He added that Syria needs "a written commitment from everybody including the imam of Saudi Arabia."
