Two bombings in Pakistan's eastern city of Lahore killed five people and injured 27 on Thursday, according to police Information Minister Sheikh Rashid Ahmed condemned the "terrorist attacks" and blamed "enemies of Pakistan."
There was no immediate claim of responsibility.
The first bomb, planted under the seat of bicycle, went off near a crowded public park, killing one person and injuring nine, three seriously.
About 90 minutes later, a second bomb went off outside a jewelry shop in a commercial district of the city, killing four people and wounding 18, police said.
"It seems the same people" are behind both attacks, said Mobin Ahmed, security police chief for Lahore, but he did not say who might be behind it or their motive.
Pakistan is often hit by bombings motivated by sectarian hatred and opposition to the government's support of the U.S.-led war on terrorism. Sometimes attacks are motivated by business disputes and political rivalry.
Mobin said the first blast was caused by a "locally made high-intensity time device."
It went off at the side of a main road in central Lahore during rush hour and caused a stampede by hundreds of panicked people inside the adjoining Manto Park, although none were injured. The road was blocked off and traffic was diverted, as police and explosives experts sifted through the debris for evidence.
Witnesses of the second blast said it caused havoc in one of Lahore's busiest bazaars, shattering windows in shops and vehicles.
Authorities were on alert and urged city residents to be vigilant and report suspicious-looking objects, the AP reports.
