Polio shootings 'kill 9' in Nigeria

Abuja - Gunmen shot dead at least nine people in Nigeria's main northern city of Kano where health workers were administering polio vaccinations, police say, in the latest in a string of violent attacks.
Islamist militant group Boko Haram - a sect which has condemned the use of Western medicine - has been blamed for carrying out a spate of assaults on security forces in the city in recent weeks.
Boko Haram wants to impose Islamic law, or sharia, on a country of 160 million split roughly equally between Christians and Muslims.
The movement is seen as the most serious threat to the stability of Africa's top energy producer.
Friday's attack will be a further setback to efforts by global health organisations to eradicate polio in Nigeria, one of only three countries, along with Pakistan and Afghanistan, where the disease remains endemic.
