KABUL, May 25 (Xinhua) -- A number of people were killed and wounded after explosions rocked Afghanistan's capital Kabul and the northern city of Mazar-i-Sharif on Wednesday, authorities said.

       In Kabul, at least two worshippers were wounded after a blast ripped through a mosque during evening prayers in Kolola Pushta locality of Police District (PD) 4, the capital police confirmed citing initial reports.

       The blast occurred when people were offering prayers in Hazrat-e-Zekria Mosque and the wounded were shifted to a nearby hospital, police spokesperson Khalid Zadran said in a tweet.

       The blast came about one hour after three consecutive explosions struck PD 10 and PD 5 in Mazar-i-Sharif. One blast hit a passenger bus carrying commuters along a busy road in the northern city.

       No group has claimed responsibility for the attacks so far.

       In recent weeks, the war-torn Asian country was hit by a series of bomb attacks reportedly staged by militants of the Islamic State (IS) group opposing the Taliban-led caretaker government.
