Colombia"s government and national strike committee, made up of major unions and student groups, reached "pre-agreements" on Monday which the government said it hopes will lead to talks to end almost a month of widespread protests.

The attorney general"s office early on Monday confirmed 17 deaths connected to protests, though one human rights group has reported more than 40 people presumably killed by security forces. read more More than a week of talks between the government and protest leaders resulted in a final document of pre-agreements late on Monday, the government said. "The session of conversations between the national government delegation and the national strike committee has today permitted the completion of a document of pre-agreements," it said in a statement, without providing further details.

"We continue in the construction of the meeting points which we hope will allow us to carry out the swift installation of negotiations," the government said.The leader of the General Work Confederation (CGT) union told media earlier on Monday pre-agreements were 90% complete.
