A huge blast struck near the entrance of Kabul's international airport on Monday during the peak lunchtime period, officials said, killing five people and wounding more than ten others.

"The explosion occurred at the first checkpoint of Kabul airport," said deputy Kabul police chief Sayyed Gul Agha Rouhani.

Taliban takfiri group claimed responsibility for the attack, which comes after a wave of lethal bombings in the capital on Friday as the insurgency escalates following a bitter power transition within the Taliban.

Taliban spokesman, Thabihollah, said in a statement that the suicide attack targeted two foreign military vehicles. However, there were no confirmation about the nationalities of the victims.

The blasts on Friday struck near an army complex, a police academy and a US special forces base, killing at least 51 people, officials said.

The wave of violence underscores Afghanistan's volatile security situation amid a faltering peace process.
