France on Tuesday issued a clarion call to the rest of the international community to act in Libya, amid growing fears the country is becoming a major "terrorist hub" on Europe's doorstep. French Defence Minister Jean-Yves Le Drian said he wanted to "sound the alarm about the seriousness of the situation in Libya." "We need to act in Libya and mobilise the international community," stressed the minister, weeks after President Francois Hollande described the chaos in Libya as his "major concern" and called for unspecified UN help in the country.
