An Afghan policeman was injured in the blast that occurred nearly 400 meters from the Indian consulate in Jalalabad city in eastern Afghanistan's Nangarhar province on Tuesday, ANI reported.

The target of the blast was not clear as consulate buildings of Pakistan and Iran are also located nearby. The house of Pakistan's Consul General is also near the blast site.

"Pakistan Consul General's house in Jalalabad was closer to the blast site than the Indian mission which was 400 metres away," PTI quoted a source as saying. 

The blast took place at around 11:30 am, according to Afghnistan's TOLO news.

The incident comes just a couple of days after the Indian consulate in Afghanistan's Mazar-i-Sharif city was attacked by a group of militants. The Afghan forces killed all the militants in a 24-hour gun battle. No one at the Indian diplomatic mission was injured in the attack.

Tuesday's blast in Jalalabad, however, was reportedly not aimed at the Indian consulate.

"The blast was reported 400 metres from the Indian consulate in Jalalabad (Afghanistan), Consulate was not the target," ANI quoted its sources as saying.

No group has claimed the responsibility for the attack as yet.

Earlier in December, the Afghanistan's National Directorate of Security (NDS) had claimed to have foiled a Taliban attack on the Indian consulate in Jalalabad
