Syria

The Syrian Observatory for Human Rights says Islamic State militants killed the seven men and three women near the besieged Kurdish town of Kobani.

Saying his country will do "whatever is needed" to help fight the extremist group ISIS, Turkey's President Recep Tayyip Erdogan says he has reached what media are calling "a point of determination."

Seven airstrikes hit in Syria and three in Iraq, according to U.S. Central Command, which adds that Saudi Arabia, Jordan and the United Arab Emirates participated in some strikes.

Many legal scholars say the White House lacks a legal justification for the strikes inside Syria. But the administration disagrees, saying its actions are covered by post-Sept. 11 legislation.

The Syrian group, which the U.S. and a coalition of Arab partners has been striking in Iraq and Syria, is estimated to get as much as $6 million a day from the oil fields it has taken over.

President Obama has been reluctant to call it a war, yet the administration and the Pentagon boast of a 40-nation coalition and warn of a military operation that could last for years.

The group, which was targeted by U.S. airstrikes in Syria last night, has been on the U.S. radar for a while. Intelligence officials say they have tracked its individual members for years.

The president praised the five Arab nations that joined in airstrikes against extremists in Syria and said it should be clear that there are "no safe havens" for those who threaten America.

The U.S. urgently needs allies on the ground in Syria. Yet it has given no sign that it's willing to work with Kurdish militias who are already fighting the Islamic State group in Syria.

As the U.S. begins to arm and train Syrian rebels, here's a look at the very mixed record of U.S. support for rebel movements from Angola to Afghanistan.

The Pentagon said it had used fighter, bomber and Tomahawk missiles during the mission launched on Monday.

Peshmerga forces say they are still engaged in fierce battles with Islamic State militants. The fighting has triggered a mass exodus of Kurdish refugees into Turkey.
