The Afghan National Directorate of Security (NDS) said on Wednesday the National Unity Government (NUG), NATO and the United Arab Emirates will probe the suicide bombing last week at the Kandahar governor's guesthouse in which five UAE diplomats were killed.
 
In a statement released by the NDS, based on the orders of President Ashraf Ghani a joint delegation of Afghan security experts in collaboration with UAE research groups and international coalition forces led by NATO have started investigations into the Kandahar guesthouse suicide bombing.
 
According to initial investigations the attack was planned outside Afghanistan, NDS said.
 
The suicide attack was plotted at a suicide training center called “Mawlawi Ahmad Qandahari” in the city of Quetta, Pakistan, the NDS said.
 
The blast occurred inside the Kandahar governor's high-security guesthouse where the UAE diplomats, including Ambassador Juma Mohammed Abdullah Al Kaabi, had gathered for dinner. No group claimed responsibility and the Taliban denied any involvement.
 
The Kandahar police chief Gen Abdul Raziq blamed the Haqqani Network while the Afghan National Security Adviser Hanif Atmar claimed that the attack was planned 'outside’ the country.
 
However, Head of General Security for the Emirate of Dubai Lt Gen Dahi Khalfan Tamim disputed the claims by the Afghan security officials and said Afghan officials are responsible.

 A UAE delegation recently visited Afghanistan to get a briefing about the circumstances that led to the serious security lapse and the progress in the investigation. An Arab diplomatic source said the UAE officials have "conveyed their serious objections at the failure of the Kandahar security officials including Gen Raziq, to ensure security for the UAE ambassador and diplomats."
 
Raziq had walked out of the guest house just three minutes before the bomb exploded inside the guest house. Sources close to the Taliban say that Taliban representatives from the Qatar office were scheduled to travel to the UAE on Sunday to meet officials and clarify that they had no role in the attack.
