At least 24 people have been killed and 42 injured as a result of a car bomb explosion that hit a bus carrying government employees in western Kabul on Monday, according to an official.

“The car bomb hit a bus carrying employees of the ministry of mines during rush hour,”Najib Danish, the interior ministry spokesman, told AFP.

This marks the latest attack to strike the Afghan capital.

No group has yet claimed responsibility for the attack. The incident, however, came as Taliban insurgents have stepped up attacks across the country in recent days.

Over the weekend, several new districts have fallen to the militants.

Kanul is regularly targeted by suicide bombs at terrorist attacks. According to a recent UN report, attacks on the Afghan capital accounted for nearly one-fifth of all civilian Afghan casualties in the first half of 2017.

1,662 civilians were killed and more than 3,500 injured in the first six months of the year, the UN Assistance Mission in Afghanistan (UNAMA) reported.

The UNAMA also reported that nearly half of Afghanistan’s 34 provinces have seen an increase in civilian deaths in the first six months of the year. The death toll is mainly due to the rise in attacks by anti-government forces across Afghanistan.
