Afghanistan blast at Kandahar wedding a 'suicide bomb'
A blast in southern Afghanistan which killed 40 people appears to have been a suicide bombing, Afghan officials say.
The explosion ripped through a wedding party in Kandahar province on Wednesday evening, leaving 70 more wounded. Children were among the casualties.
Reports said many of the guests had links to local police or an anti-Taliban militia and that is why they were targeted.
The Taliban, however, have denied any involvement in the attack.
Last week, Afghanistan held a national peace council and endorsed a plan to seek peace with the Taliban. But violence has continued unabated.

The explosion ripped through the wedding party at about 2100 local time (1630GMT).
The guests had gathered in Arghandab district just north of the provincial capital of Kandahar, news agency Associated Press quoted Afghan interior ministry spokesman Zemeri Bashary as saying.
Mr Bashary said it was a suicide attack.
