Amnesty International today issued a chilling report revealing the pervasive use of torture on civilians by government forces while in Damascus. The visiting UN envoy is set to weigh in on Assad's response to the UN-proposed peace plan, according to Reuters.

The embattled Syrian leader was recently given what Annan described as "concrete proposals" for ending the violence there -- which has continued unabated since Annan's arrival over the weekend -- and is now considering the Assad's response.

Annan's spokesman, Ahmad Fawzi, told Reuters that the UN representative "will have more to say later today."

The report from Amnesty International comes a day after Human Rights Watch said Assad's forces are positioning landmines along the country's Turkish and Lebanese borders in order to block routes used by those fleeing violent political upheaval that has taken the lives of over 8,000 people, reported the BBC.

Amnesty International cites a total of 31 methods of torture being used by the authorities. The group also says it is also investigating "some reports of abuses" by armed opposition groups, recommending that the human rights situation there fall under the purview of the International Criminal Court.

Al Jazeera however notes this would require the approval of the UN Security Council, a group that has been unable to reach a consensus on Syria due to resistance from veto-weilding members Russia and China.

The revolt against Assad's regime in Syria is entering its first-year anniversary amid continued bloodshed, despite efforts by the international community to end the government's brutal crackdown on unrest.

Assad's forces on Tuesday reclaiming the rebel holdout of Idlib, which lies near the Turkish border, and Reuters today reports fresh violence in the southern city of Deraa.

World leaders, meanwhile, continue to raise concerns about the situation in Syria, a strategic country with a diverse population nestled between Turkey, Jordan, Israel, Iraq and Lebanon.

Britain's Prime Minister David Cameron is to discuss Syria during talks with US President Obama today while on his three-day US tour, telling reporters today that "the shortest way of ending the violence is a transition where Assad goes, rather than a revolution from the bottom," according to The Telegraph.

The UN said Tuesday it is sending human rights monitors into Syria's border countries to collect eyewitness testimony on abuses there, said Reuters.
