Britain planning troops to Somalia, South Sudan to join peacekeeping mission against militants

Britain's prime minister says more than 300 British troops will be deployed to South Sudan and Somalia as part of peacekeeping efforts to counter Islamic militants.

David Cameron says up to 70 personnel could be sent to Somalia to bolster a United Nations-backed mission to push back against al-Shabab extremists. A further 250 to 300 could also be deployed in troubled South Sudan.

The forces will provide combat training and medical, logistical and engineering support. Final numbers will still need to be negotiated with the U.N.

Cameron said Monday that Britain wants to "step up" its role and work toward "less terrorism, less migration, less piracy" in Somalia.

It would be the first time Britain has formally joined the international contingent backing the African Union's long-running efforts against al-Shabab.
