GENEVA - At least 191,369 people have been killed in Syria's conflict through April, more than double the figure documented a year ago and probably still an under-estimate, the United Nations human rights office said on Friday.

The UN report, based on data from four groups and the government that were cross-checked, reflects a reality of killing and torture while the civil war has "dropped off the international radar", U.N. High Commissioner for Human Rights Navi Pillay said.

"With additional killings reported from earlier periods, in addition to the new killings that have taken place, the total is more than double the number documented a year ago," Pillay said in a statement.
