Islamic State video purportedly shows killing of 30 Christians in Libya
A video purportedly made by Islamic State and posted on social media sites on Sunday appeared to show militants shooting and beheading about 30 Ethiopian Christians in Libya.
Reuters was unable to verify the authenticity of the video, but the killings resemble past violence carried out by Islamic State, an ultra-hardline group that has expanded its reach from strongholds in Iraq and Syria to conflict-ridden Libya.
The US issued a statement condemning the killings.
The video, in which militants call Christians "crusaders" who are out to kill Muslims, showed about 15 men being beheaded on a beach and another group of the same size, in an area of shrubland, being shot in the head.

Both groups of men are referred to in a subtitle as "worshippers of the cross belonging to the hostile Ethiopian church".
Libyan officials were not immediately available for comment.
Ethiopia said it had not been able to verify whether the people shown in the video were its citizens.
"Nonetheless, the Ethiopian government condemns the atrocious act," government spokesman Redwan Hussein said.
He said Ethiopia, which does not have an embassy in Libya, would help repatriate Ethiopians if they wanted to leave Libya.
The United States also condemned the "brutal mass murder," with the White House saying the killing of the men "solely because of their faith lays bare the terrorists' vicious, senseless brutality."
Militants professing loyalty to Islamic State have claimed several attacks on foreigners in Libya this year, including an assault on the Corinthia Hotel in Tripoli and the beheading of 21 Egyptian Christians in February.

The killing of the Egyptians prompted Egyptian President Abdel Fattah al-Sisi to order air strikes on Islamic State targets in Libya.
In the latest video, a man dressed in black clutching a pistol stood behind some of the victims.
"Muslim blood shed under the hands of your religions is not cheap," he says. "To the nation of the cross: We are now back again."
The video warns that Christians will not be safe unless they embrace Islam or pay protection money.
Islamic State controls large parts of Iraq and Syria and wants to redraw the map of the Middle East. It is not clear how many fighters it has in Libya, an oil-producing nation.
Egyptian security officials estimate that thousands of militants who share Islamic State's ideology moved from the Sinai Peninsula to Libya after the army toppled President Mohamed Mursi of the Muslim Brotherhood in 2013.
