KABUL, Afghanistan — Three explosions on Saturday rocked the funeral service of a victim of antigovernment protests in Kabul, killing at least seven people and injuring dozens after a tense and bloody week in the Afghan capital.

The blast followed a truck explosion on Wednesday that killed nearly 100 people and wounded almost 500 near the presidential palace and foreign embassies.

The number of casualties on Saturday was not immediately clear, but Wahidullah Majroh, a spokesman for the Health Ministry, said seven bodies had been recovered and 119 people had been taken to hospitals with injuries.

Local news media reported that at least 12 people had been killed, and the Emergency Hospital, one of Kabul’s main trauma centers, put the number of dead at 19.
