Solidarity with migrants in the city of Calais - a migrant bottleneck in Europe - is not limited to organisations, reports IPS Africa. 'Some local residents have also become involved on an individual basis with the transient foreign population that has passed through the city.

We, members of the Feminist Activist Coalition, comprising of over 40 civil society organisations promoting gender equity, social justice, human rights and the transformative feminist movement are outraged over the arrest of 16 activists on 9 February 2012 in Dar es Salaam and their subsequent indictment, purportedly for holding an unlawful assembly.

The World Socialist Website reports on German study published by the government on young muslims in the country. The study’s publication has become the occasion for a renewed campaign against immigrant communities in Germany. A 'deliberate political campaign seeks to limit the study’s findings to that which can be exploited for the dissemination of xenophobic sentiments. In fact, the 750-page report provides a much more nuanced picture. The fact that the researchers are critical of the government’s integration policy is being swept under the carpet.'

The working class energies and aspirations that poured out onto South Africa’s streets are one loud clear statement: government must listen to the people as its neo-liberal policies continue to make the rich richer and to impoverish the majority.

Cosatu is expecting a massive turnout for its national strike on Wednesday, and even hopes organisations outside of its network may spontaneously join in - but the union group has been wary of talking numbers, saying the dual nature of Wednesday's action makes turnout even more unpredictable than is usual in such actions. Based on discussions around labour broking within Nedlac, however, it said it believes unions not aligned with it may join in, as might taxpayer groups concerned about road tolls.

The World Development Movement has warned that the UK’s new drive to provide aid to Somalia is looking like a ‘cynical’ attempt to grab its oil, rather than being aimed at ensuring a better future for people in one of the world’s poorest countries. A report in the Observer newspaper on Sunday revealed that UK officials have been engaged in secret negotiations with Somali leaders to secure access to the country’s immense oil reserves. The revelation came after the UK announced a large aid package for Somalia, and David Cameron hosted a conference in London last week on the development of the war torn state.
