Thousands have joined Afghan President Hamid Karzai to mourn at the funeral of his half-brother near Kandahar, BBC reported.
Ahmad Wali Karzai, a controversial but key figure in Nato's battle against the Taliban, was gunned down at home by his bodyguard on Tuesday.
Bus-loads of mourners followed the body from the provincial governor's compound to his family village of Karz, some 20km (12 miles) away.
Security was tight, with helicopters overhead and many troops deployed.
Karzai was shot twice by his family friend and long-time head of security, Sardar Mohammed, who was himself killed almost immediately, in an attack claimed by the Taliban as one of their top achievements in 10 years of war.
