At least ten people have been killed and over a dozen injured as three bombs went off in Afghan capital Kabul. The Taliban, the main Afghan insurgent group, has denied its involvement in the explosions. 

Two bombs exploded within minutes after each other on Tuesday evening in the western part of the capital, targeting two buses carrying mostly daily laborers, confirmed Tariq Arian, the spokesperson of the country’s interior ministry. The bombs killed at least ten people and wounded over a dozen. 

The third bomb targeted an electric grid station in the capital, TOLOnews reported. 

Those killed were mostly daily wage earners from the west Kabul area, a region that is dominated by Shia Hazara ethnic minority. The area often comes under attack from insurgents. Earlier on 8 May, a girls' school in the same locality was targeted where over 100 people, mostly girls students, had been killed. 

Targeted attacks on the Afghan Hazara ethnic minority have become more frequent lately as foreign troops are on their way out. The fear among the community --of the country descending into a civil war-- is real and, even more so, when they carry the history of persecution on ethnic lines.    

In the last few years, ISIS-- a recent entrant into the Afghan conflict-- often mount attacks on the community. 

In a separate incident of a bombing on Wednesday morning, a roadside bomb targeted a convoy of soldiers of the NDS, the Afghan intelligence agency, in the eastern city of Jalalabad. Two civilians were killed in the incident and ten suffered injuries, according to a report in TOLOnews. 

No group, including the Taliban, has taken responsibility for the attack so far. 

The fighting between the Taliban and the Afghan security forces has intensified in recent days, with around 28 out of its total 34 provinces reporting daily fighting. 

Baghlan, a northern province in Afghanistan, has been witnessing heavy clashes, resulting in the displacement of over 21000 people to Pul-e-Khurmi, the provincial capital, confirmed the United Nations Office for the Coordination of Humanitarian Assistance in a report. 

Media reports also indicate that Afghan cities, especially provincial capitals, are now flooded with internally displaced people (IDP) as fighting intensifies in rural areas.
