Unite, Unison, the Public and Commercial Services Union (PCS) and the Scottish TUC have all called for halt to the air attacks on Libya.

For the first time in more than 60 years, Western control over the world's biggest pots of oil was being rocked by a series of revolutions our governments couldn't control. The attack on Libya, says Johann Hari, is a way of asserting raw Western power, and trying to arrange the fallout in our favour.

Western military action against Gaddafi risks spreading the conflict and undermining the democratic movement, says Seumas Milne. It will be seen as another round of colonialism.
