The attack on a Mali hotel claimed by al-Qaida may have been partly aimed at asserting the global terror network’s relevance as it faces an unprecedented challenge from the Islamic State (ISIS) for leadership of the global jihadi movement.

An airstrike has killed a top al-Qaida commander and two other fighters in Syria.

Islamic State militants invaded Iraq’s west almost a year ago and overran the nation’s second-largest city in June, threatening death and torture to opponents in their way. But the world has been slow to respond, coming together Wednesday for the first high-level meeting of scores of nations now devoted to destroying the rampant insurgency.

During a key battle in the rugged mountains of a northern province earlier this month, U.S.-backed Syrian rebels collapsed before an assault by al-Qaeda fighters. Some surrendered their weapons. Others outright defected to the militants.

America’s top military leader arrived in Iraq on Saturday on a previously unannounced visit, his first since a U.S.-led coalition began launching airstrikes against the extremist Islamic State group.

The Pentagon warned Congress on Thursday that the long, drawn-out military campaign against Islamic State militants is just beginning and could expand to include modest numbers of U.S. forces fighting alongside Iraqi troops.

US-led coalition airstrikes against the Islamic State group and other extremists in Syria have killed more than 860 people, including civilians, since they began in mid-September, a monitoring group said Wednesday.

Islamic State group extremists lined up and shot dead at least 50 Iraqi tribesmen, women and children Sunday, officials said, the latest mass slaying by militants who have killed some 150 members of the tribe in recent days.

Dozens of Iraq’s Kurdish peshmerga fighters will fly to Turkey on Tuesday and from there cross into the Syrian border town of Kobani to help fellow Kurds fight Muslim militants, a spokesman for the Kurdish force said.

Lawmakers in Iraq’s largely autonomous Kurdish region Wednesday authorized peshmerga forces to go to neighboring Syria and help fellow Kurds combat Islamic State militants in the key border town of Kobani, providing much-needed boots on the ground.

Syrian President Bashar Assad is taking advantage of the US-led coalition’s war against the Islamic State group to pursue a withering air and ground campaign against more mainstream rebels elsewhere in the country, trying to recapture areas considered more crucial to the survival of his government.

Islamic State group fighters seized at least one cache of weapons airdropped by U.S.-led coalition forces that were meant to supply Kurdish militiamen battling the extremist group in a border town, activists said Tuesday.

In a period of about six weeks spanning August and September 2014, President Obama dramatically revamped his Middle East policy to put degrading and destroying the Islamic State (ISIS) at its center.

The Kurds of Syria and Iraq have become a major focal point in the war against the Islamic State group, with Kurdish populations in both countries coming under significant threat by the militants’ lightening advance.

Intensified U.S.-led airstrikes and a determined Kurdish military force on the ground appear to have had some success in halting advances by Islamic State fighters on a strategic Kurdish town near Syria’s border with Turkey — at least for now.

It may be less punchy than previous nicknames for U.S. conflicts in the Middle East—remember Operation Desert Storm and its thunderous attacks on Saddam Hussein’s occupation army—but the Pentagon has finally named its fight against Islamic State militants in Iraq and Syria: Operation Inherent Resolve.

President Barack Obama and military chiefs from more than 20 nations gathered Tuesday in a show of strength against Islamic State fighters in Iraq and Syria. But the alliance faced a fresh test as Turkey launched airstrikes against Kurdish rebels inside its borders, defying pleas from the U.S. to instead focus on the IS.

“In London we’re very, very vigilant and very, very concerned,” said London Mayor Boris Johnson.

On the western edge of Iraq’s capital, Islamic State group militants battle government forces and exchange mortar fire, only adding to the sense of siege in Baghdad despite airstrikes by a U.S.-led coalition.

The barrage of U.S. cruise missiles last month aimed at a Syrian terroristcell killed just one or two key militants, according to American intelligence officials who say the group of veteran al-Qaeda fighters is still believed to be plotting attacks against U.S. and European targets.
