KABUL, Afghanistan — As law students waited outside Kabul University to take fourth-year exams shortly after daybreak on Friday, a suicide bomber drove up and detonated an explosive device, killing 10 people and wounding 33.

The bombing was the latest in an aggressive series of attacks by insurgents in the 10 days since American and Taliban negotiators suspended peace talks in Doha, Qatar, that were aimed at reaching a political settlement and a cease-fire in the 18-year-old war.

The Interior Ministry blamed the Taliban for Friday’s attack, which killed students and a traffic officer. A Taliban spokesman denied that the group was involved in the bombing, although it has claimed responsibility for many recent attacks.

In a burst of violence noteworthy even by Afghan standards, the Taliban have launched a number of sophisticated attacks aimed at government security forces and compounds, in some cases killing and maiming civilians.
