It is standard procedure for terrorists in Iraq, Pakistan, and now Afghanistan. After a high profile terrorist attack, show up at the funerals and repeat the atrocity.
For the distinguished guests clustered on the side of the vast carpeted prayer hall - including Kandahar's governor and four of Karzai's brothers - a meal was ready across town at Mandigak palace, where the provincial council meets, the cleric said. The others could eat in the mosque, served by the boys scattered around the room.
As the guests stood to leave, a bomb hidden inside a man's turban detonated, killing at least four people and wounding 15 others, according to Afghan officials and witnesses.
The attack defied stringent security measures - checkpoints and road blocks surrounded the mosque, and some guests said they were searched three times before entering - that were put in place after Ahmed Wali Karzai was shot dead at his home by a trusted confidant on Tuesday.
People who attended the service noted that turbans, which are common in Afghanistan, are generally not part of a body search.
There is something particularly demoralizing about this tactic - mourners, already emotionally devastated by one loss, experience more loss right before their eyes.
The capacity of the terrorists to invent new ways to psychologically harm us appears to be without end.
