At least 10 people were killed and several wounded in an explosion near police offices and a mosque in Afghanistan's Herat province, police officials told Al Jazeera.
Abdul Ahid Wali Zada, police spokesperson, said the bomb was planted in a rickshaw that detonated near the Jama Masjid, a large mosque dating from the 12th century in Herat city on Tuesday.
"The death toll coud rise," he said.
There was no immediate claim of responsibility. Zabihullah Mujahid, a spokesman for the Taliban, told Al Jazeera that the group was not involved in the attack.
Images posted to social media showed plumes of black smoke rising above a mosque complex.
The reports came after a string of recent attacks in Afghanistan's capital, Kabul, and as President Ashraf Ghani hosted a summit on security.
On May 31, at least 150 people were killed when a truck loaded with explosives detonated in a fortified area of the city near several foreign embassies.
