Six people wounded at the bar were hospitalized, while three people wounded in the second grenade attack had to be hospitalized.
The other people wounded in the attacks were treated at the scene.

Mayor assassinated in Hidalgo, Tamauliapas
Unidentified gunmen murdered the mayor of a small town in the Mexican border state of Tamaulipas where 72 migrants were massacred last week, a source in the state prosecutor's office said on Sunday.
'They've just killed the municipal president (mayor) of Hidalgo,' the source told AFP, speaking on condition of anonymity.
Marco Antonio Leal Garcia, 46, was shot dead while he was driving his car, the source said. His four-year-old daughter was seriously wounded in the attack, the source said.
Leal Garcia had taken office in January 2008 and was supposed to step down on December 31. The town of 25,000 people is located 90km northwest of the state capital, Ciudad Victoria.
His predecessor was seriously wounded in an attack a year ago, and a police officer was killed in March in a machine-gun and grenade attack on the mayor's residence.
The state has been hit by five attacks involving explosives since the discovery on Tuesday of the bodies of 72 migrants who had been massacred at a Tamaulipas ranch, allegedly by a notoriously violent drug trafficking gang call Los Zetas.
