This is the Global News podcast from the BBC World Service. I'm Jeanette Jaliel and in the early

hours of Friday the 3rd of January, these are our main stories. The FBI says it now believes

the man who killed 14 people in a car ramming attack in the US city of New Orleans on New Year's

Day acted alone. 1500 migrants have set off with the United States from southern Mexico, hoping to get

there before Donald Trump becomes president and titans border controls.

Syria's new rulers carry out a crackdown in the city of Homs, targeting what they say

are pro-Assad war criminals.

in the city. The FBI has now said it's confident that the suspect Shamsuddin Jabbar was acting

alone. He died in exchange of gunfire with the police. Initially in the hours after the attack on

crowds celebrating the new year,

investigators said they feared he'd had accomplices. The 42-year-old from Texas is believed to have

Tom Bateman sent this report. Footage has emerged from the moment of the attack,

showing the white Ford pickup truck careering down Bourbon Street.

People scramble out of its path, some only just escaping with their lives.

The FBI probe is now focusing on Shamsudin Jabar, an American born in Texas who spent more than a decade in the US military, including a year-long deployment in Afghanistan.
