Militants fighting the Syrian government threatened to wage war against the United States and the United Kingdom.

In a video posted on the Internet, the foreign militants said the US and the UK would be the next targets of their militancy.

Earlier on Wednesday, US channel, Fox news, reported that extremists who are pouring into Syria could threaten US in future.

It quoted a key US lawmaker who receives regular briefings on the issue, as saying that most of the more than 1,000 extremists who have poured into Syria to fight alongside Al Qaeda carry passports from North America and Europe, raising the possibility that they could easily bring terror back to the west.

The prospect is especially chilling given that Al Qaeda-linked fighters in Syria seem determined to use the embattled nation as a haven from which to launch future attacks beyond the region, according to Rep. Mike Rogers, R-Mich., who chairs the House Intelligence Committee,” Fox news reported.

"The number now exceeds 1,000 western jihadists who have shown up, so they'll have passports, good passports, allows them to travel around Europe, maybe get to the United States," Rogers told Fox News. "That's concerning."
