Fourteen people were wounded when a club in downtown Nairobi came under a grenade attack, local media reported early Monday. The wounded have sent to hospital, the reports said, adding that the attack was suspected to be linked to Kenya\'s recent operations against Al-Shabaab militants in Somalia. Kenyan troops made further advances into Somali Al-Shabaab controlled territory on Saturday, with the support of heavy aerial bombardment. Somali militants have vowed to retaliate.
