Death toll of Friday's wave of attacks in Kabul killed at least 50 people and wounded hundreds, the BBC reported Saturday.

Security has been stepped up in the Afghan capital after the fresh series of bomb attacks.

The UN said the attacks were likely to be the product of a Taliban power struggle following the death of its leader Mullah Omar.

The attacks, which happened within 24 hours of each other and injured hundreds, are the first major incidents since the Taliban confirmed last week he had died two years ago.

President Ashraf Ghani is due to hold a meeting of the National Security Council on Saturday to discuss the worsening situation and Afghan soldiers have been deployed across the capital to boost security.
