The Colombian government and the Revolutionary Armed Forces of Colombia, also known as FARC, announced a new peace agreement Saturday, almost two months after Colombian voters narrowly rejected an earlier deal.

Negotiators announced the breakthrough in The two sides first reached an agreement after four years of negotiations in September, but the original deal fell apart after its defeat in an October referendum. The New York Times has more:

The latest agreement aims to address some of the concerns of opponents of the original accord, especially former President Alvaro Uribe who said the deal was too lenient on a rebel group that had kidnapped and committed war crimes.

"The new deal is an opportunity to clear up doubts, but above all to unite us," said chief government negotiator Humberto de La Calle, who signed the accord along with rebel negotiator Luciano Marin, alias Ivan Marquez, in Cuba, moving to end a half-century-long conflict that has claimed more than 220,000 lives.

De la Calle described the text of the modified accord as "much better" than the previous one, but didn't say if or how it would be submitted to a referendum.

Both sides agreed to preserve the ceasefire while negotiations continued. If successful, the new accord would end the last armed conflict in the Western Hemisphere.

A Taliban suicide bomber killed two U.S. soldiers and two American contractors at Afghanistan’s Bagram Air Base on Saturday.

The bomber, who wore a suicide vest, bypassed extensive security at the largest NATO base in the country. The attack comes two days after truck bomb struck a German consulate in northern Afghanistan, killing two people. NBC News has more:

The attack occurred around 5:30 a.m. local time as people were gathering for a post-Veterans Day fun run.

There was no immediate word on the identities of the victims. The Taliban claimed responsibility for the blast, according to The Associated Press, which quoted a spokesman who said they have been planning the coordinated carnage for four months.

The suicide bomber chose the time and location because he "was looking for an opportunity to do the most damage," a senior U.S. military official told NBC News.

Sixteen U.S. soldiers and a Polish soldier were also injured in the attack. In a statement shortly after the bombing, the U.S. embassy in Kabul also said it would be closed Sunday as a “temporary precautionary measure.”
