More than 200 Moroccans have been detained at Algeria's main airport after trying to travel to Libya, where Islamic State militants are building a new caliphate.

The men were stopped at Algiers airport on Saturday night and were considered suspicious because they did not have legal residence in Libya.

Algeria's government said it had also summoned the Moroccan envoy to explain a "sudden increase" in people attempting the journey.

It comes as the Islamic State of the Iraq and the Levant (Isil) announced it was trying to recruit more jihadists from North African countries to extend its influence over the continent.

"The question about the massive and unusual flow of Moroccans from Casablanca heading for Libya through Algeria in the last weeks was the reason for discussions with the ambassador," a spokesman for Algeria's foreign ministry said.

The ministry said it was facing a “particularly delicate” situation which needed better vigilance and cooperation from its neighbouring countries.

Isil has been steadily in increasing its presence in Libya, prompting neighbouring Tunisia to build a security wall across its border in the hopes ofstemming the flow of new IS recruits.
