NBC News Chief Foreign Correspondent Richard Engel, who is in the Afghan capital Kabul, wrote on Twitter:
The Taliban have claimed responsibility for a rocket attack on the Independent Election Commission (IEC) in the Afghan capital Kabul.
This is the second attack launched against an IEC office this week, as the Islamist insurgency seeks to derail the April 5 election it claims is a "Western-backed sham".
Armed men have attacked the Afghan election commission with rockets and gunfire one week before the presidential elections begin.
One warehouse in the compound is currently on fire after it was hit by a rocket-propelled grenade, Associated Press reported.
Police Chief General Mohammad Zahir said the group entered a building 800 metres (2,624 feet) from the Independent Election Commission, adding, "The fighting is still ongoing."
Heavy security has been sent to the Independent Election Commission headquarters in Kabul as gunfire and blasts were reported around the building compound.
