Beirut: Violence in Syria continued on Saturday with a suicide truck bomb killing three civilians and one security officer in the central province of Hama.
According to Syria`s state news agency, SANA, the attacker had covered the bomb with onions.
The bomb that was detonated in the town of Muhrada targeted the local military security headquarters, said the anti-regime Syrian Observatory for Human Rights.
The dead included two women and a child.
In the meantime, a team of UN observers has finally made it to near the Syrian village of Tremseh, the site of latest massacre.
Up to 200 people were reportedly killed by government forces this week in Tremseh.
According to pictures and videos posted online, UN vehicles were seen surrounded by citizens who showed them blood-stained clothes of victims.
"These are Russian weapons," shouted an angry man in the video.
The international community has condemned the massacre, which the United Nations has blamed on Syrian forces.
The United States has branded Syria`s leaders murderers after an attack on a village by President Bashar al-Assad`s troops left dozens dead.
United Nations Secretary-General Ban Ki-moon also condemned what his monitors on the ground had seen as an "indiscriminate" bombardment that included rocket-firing helicopters of the town of Tremseh in rebellious Hama province, and he questioned Assad`s commitment to a UN-sponsored peace plan for Syria.
Scores of people were killed on Thursday when Syrian gunners bombarded the impoverished village of Tremseh with tanks and helicopters in what rebels claim was among the worst single days of bloodshed in the uprising against President Bashar Assad.
The accounts of the killings and death tolls varied widely. Late Friday, local activists backed away from early reports that more than 200 people were killed. One said he had confirmed 74, but had only 20 names. Another provided a list of 103 names.
For its part, the Syrian government said more than 50 people were killed when Syrian forces clashed with "armed gangs" that were terrorising village residents. The regime refers to its opponents as terrorists and gangsters.
