The International Rescue Committee is temporarily suspending its operations in Afghanistan following the brutal killing of five of its local staff members, the latest in a string of violent attacks against aid groups in the country in just about three months. The aid workers, who were in their 20s, were part of a development project in Herat province under the Afghan government’s National Solidarity Program, of which IRC is a facilitating partner.

Colombia's police are already strategizing for the end of the country's conflict with Marxist rebels, even as the task of combating the guerrillas is increasingly falling to the police instead of the military. With talks between the Colombian government and the Revolutionary Armed Forces of Colombia (FARC) now almost a year old, General Jose Roberto Leon Riaño, who was director of the Colombian National Police until earlier this month, declared "the new model of service [for the police] is anticipating a post-conflict scenario, a scenario of peace."

Last week, it was brought to a lot of people's attention that al Qaeda were active on Twitter. This was slightly less surprising than it sounds. At a grassroots level, these early masters of the viral beheading video know social media's black magic well enough, which is probably why they decided to crowdsource ideas of how they could improve their online image.

With the bloodbath in Egypt, ongoing carnage in Syria, and gruesome bombings in Iraq, another explosion in the Middle East might hardly seem like news. But the importance of the blast that rocked Beirut’s southern Shia-dominated suburbs on August 15, killing around 20 people and wounding hundreds more, should not be diminished. It could spell the beginning of the end for Hezbollah, the dominant political-military actor in Lebanon and one of the United States’ most powerful nemeses in the region.

#you_tried. A jihadist Twitter account tried to solicit suggestions from the al Qaeda community Wednesday by creating the hashtag #اقتراحك_لتطوير_الإعلام_الجهادي, which roughly translates to #Suggestions_to_develop_Jihadist_media, according to a linguist fluent in Arabic who translated it for Business Insider.

There's a new jihadist recruiter on the Internet. Based in San Francisco and backed by a multimillion dollar bankroll, the recruiter orchestrates thousands of introductions every day, connecting people at risk of radicalization with extremist clerics and terrorist propagandists -- even facilitating online meetings with hardcore al Qaeda members. The recruiter is Twitter, and it's shaking up the world of online radicalization in ways both large and small.

Very little coherent information is currently coming out of the parts of northern Nigeria under a state of emergency. What information is available indicates that activity and violence continue under the cover of the media silence, though it is difficult to judge its degree. In May, cell phones and satellite phones did not operate in the affected areas. Those services are only slowly being restored. Foreign media are almost entirely absent, and domestic media appear to be highly restricted. Foreign diplomats do not travel there.

The twelfth round of peace talks between the Colombian government and FARC rebels ended on Saturday in Havana, Cuba with both sides expressing optimism despite a lack of recent concrete actions and agreements in the past week. Current negotiations, which began in October 2012, have been more successful than previous attempts, with difficult obstacles like land reform having reportedly been cleared.
