Two bomb attacks claimed the lives of five people and injured 14 others in northern Afghanistan on Thursday, officials confirmed.

The first attack took place in Kunduz city, the capital of Kunduz province 250 km north of Afghan capital Kabul, killing three people and injuring four others, police said.

"A vehicle of National Directorate for Security (NDS) was running in Bandar-e-Kabul area of the city when a sticky bomb attached to the vehicle by militants went off at 07:00 a.m. local time, killing one NDS personnel aboard and two civilian passersby on the spot," a police official told Xinhua but declined to be named.

Four more people sustained injuries and several shops and houses were damaged nearby in the blast, he added.

The NDS is the intelligence agency of the country.

Hour later in a similar bombing in Aqcha district of Jauzjan province 390 km north of Kabul, two people lost their lives and 10 others got wounded.

"A bomb planted by the armed militants in Aqcha district and detonated at around 08:00 a.m. local time left two people including a police dead and injured 10 others including four policemen," a local official told Xinhua but declined to be identified.

The police chief of Aqcha district Jawad Jahid said the enemies of peace, a reference to Taliban militants, planed explosive device on a rickshaw and detonated it next to a police vehicle inflicting casualties.

The Taliban announced recently to step up attacks on Afghan and foreign troops during the Muslim fasting month of Ramadan.
