talks in Cuba progress between the government and the FARC . Pipelines are usually brought back on line within a matter of days after attacks , which in 2012 were as regular as one every two or three days , almost twice as frequent as in 2011 . The first explosion on the 780-km ( 485 mile ) pipeline happened on Thursday near El Tarra in Santander province and the second on Friday , near Saravena in Arauca province .

Protest organizers in Samarra blamed Shi ' ite militia for the bombing and said security forces were complicit as the explosives-packed vehicle had passed through several checkpoints . Protesters ' demands range from amending laws they say are used unfairly to
