Bomb blasts that rocked the Northeastern Nigerian city of Maiduguri have killed at least three people, including a policeman, and wounded 15, police said on Monday.
They reported a fresh explosion on Monday morning when a bomb was tossed at one of its patrol vans, leaving one policeman wounded, the day after two blasts hit a hotel and a transport hub.
"From our records the death toll has risen to three, which include a police corporal and two civilians who were at the tavern to have some drinks," police commissioner Mike Zuokumor told AFP.
He said 14 people in total, including two children playing outside the hotel tavern, were wounded in the blast.
"We also had another bomb blast this morning targeting a police team. Two attackers on a motorbike threw a locally made bomb at the patrol van, seriously injuring a policeman on duty," said Zuokumor.
The attackers fled via an alleyway.
Police had earlier blamed an Islamist sect known as Boko Haram for the three bomb blasts on Easter on Sunday night.
Apart from the Monday morning incident, Zuokumor said all the casualties counted so far were from the hotel.
The blasts come ahead of governorship elections in most of Nigeria's 36 states on Tuesday and after last week's deadly unrest in the wake of presidential elections that a local rights group says left more than 500 dead.
