Meanwhile, Lieberman US senator voiced his support for the Syrian opposition Wednesday, following meetings with top Lebanese officials and a visit to Syrian refugees in northern Lebanon.

Lieberman visited the northern Lebanese region of Wadi Khaled escoted by the Lebanese army, which is located near the Syrian border and houses the majority of an estimated 24,000 Syrians who have sought refuge in Lebanon, according to AFP.

Most independent media are barred from Syria or have their movements restricted, making it hard to verify such reports.Lebanon needs to help the Syrian opposition and offer further assistance to refugees fleeing unrest in their home country, U.S. Senator Joseph Lieberman, who is on an official visit to Lebanon along with U.S. official Jeffrey Feltman, said Wednesday.

Lieberman also expressed concern that countries in the region and around the world were not doing enough to back the Syrian opposition.

Massive protests were reported in several neighborhoods in the capital Damascus, the biggest of which was reported in al-Salheiya region, Al Arabiya reported citing Syrian activists.

 Random shootings were reported in al-Hamama village in Idlib, activists said, and mortar shells hit Rastan in Homs.

New York-based Human Rights Watch (HRW) condemned and accused Syrian government forces killed at least 95 civilians and burned or destroyed hundreds of houses during a two-week offensive in northern Idlib governorate shortly before the ceasefire, Human Rights Watch said in a report released Wednesday. The attacks happened in late March and early April, as United Nations special envoy Kofi Annan was negotiating with the Syrian government to end the fighting.

“As the conflict continues, Syrians in areas affected by the violence are struggling to feed their families and WFP is deeply concerned about the potential for food insecurity,” said WFP Executive Director Ertharin Cousin.

In a statement, the U.N.’s World Food Program (WFP) said that it was expanding its assistance at the request of the Syrian Arab Red Crescent and stood ready to increase its humanitarian mission in the country further “when access permits.”

U.N. aid agencies have been banned from entering Syria but a joint assessment mission carried out last month with Syrian authorities estimated that at least one million people needed humanitarian aid, reuters reports.

WFP has been providing food assistance for up to 100,000 people a month in cities such as Homs, Hama, Idleb and Damascus. It also began distributing food to Syrian refugees living in neighbouring Jordan.

WFP’s emergency operation for Syria began in August 2011 with a budget currently estimated at US$37.4 million and it is still seeking funding, as so far less than half that amount has been secured.

More than 9,000 people have died in Syria in 13 months of fighting sparked by a popular uprising against President Bashar al-Assad. The U.N. Security Council approved on Saturday the deployment of up to 300 unarmed military observers to monitor a ceasefire which remains “incomplete” according to Secretary-Genral, Ban Ki Moon.

Nearly 60 people were killed on Monday in violence across Syria, the majority of them civilians in the central city of Hama, according to the Syrian Local Coordination Committee, on Tuesday.
