Wave of Killings Threatens Colombia Peace Bid

A violent backlash against fragile peace efforts to end Colombia's half-century civil war has intensified in recent days with the killings of numerous community leaders, officials and rebels warned on Monday.

The government and leftist FARC rebels are closer than they have ever been to sealing a historic peace accord, but violence appears to have resurged in places as that deal has faltered.

Observers from the Organization of American States said Sunday that civil organizations in conflict areas reported 33 of their leaders killed this year, including several in recent days.

Just over a week ago Colombia's government said it had drawn up a revised peace deal to end the 52-year civil war with the FARC leftist rebels.

But remnants of right-wing paramilitary groups who took part in the many-sided conflict are said to remain active.

"A new genocide is taking place against civil and rural leaders," the FARC said in an open letter to Colombian President Juan Manuel Santos today.

It said three such victims had been killed and two other "attacks" launched in the past two days alone.

The FARC described them as "selective, politically-motivated killings" by parties opposed to the peace process.

That was an apparent reference to the right-wing armed groups and their supporters.

Voters rejected an earlier version of the peace plan in a referendum last month.

Opposition to that accord was led by conservative former president Alvaro Uribe.

The government hopes with Uribe's backing to bring the new agreement into force quickly.

A two-way ceasefire between the government and FARC has been in force since August. But the sides have warned it is fragile.

The FARC called in its letter Monday for the immediate application of security guarantees in the planned peace accord to protect people in conflict zones.

Santos vowed on Twitter "to take action against crimes and attacks on social leaders."

Fears for the ceasefire had already risen last week when two FARC guerrillas were killed in what authorities said was a clash with the army.

The conflict has killed 260,000 people, according to authorities.
