At least two people have been killed and over 100 others injured in two explosions during a pro-Kurdish rally in the southeastern Turkish province of Diyarbakır.
The explosions occurred with a five-minute interval during the protest rally organized by the People’s Democratic Party (HDP) on Friday, only two days before the country's parliamentary elections.
Initial reports said a malfunctioning power distribution unit caused the blasts, but Turkish Energy Minister Taner Yıldız later rejected the claim.
"There was an external intervention to the power distribution unit," Yıldız said, adding, "Our inspection has clearly showed that the source of the explosion was not the power distribution unit. Its door was damaged with pressure coming from outside to inside and not vice versa."
Following the blasts, police clashed with some of the participants in the rally and used a water canon to disperse the crowd.
Later on Friday, Turkish Prime Minister Ahmet Davutoğlu pledged to investigate the cause of the blasts.
"We will look into whether it is a power distribution unit explosion or an assassination [attempt], or any kind of provocation, and we will announce the result as soon as possible," he said following the incidents.
The explosions mark the latest in a series of raids against the HDP across Turkey. Earlier this week, gunmen attacked a campaign vehicle belonging to the HDP in the Kurdish-majority province of Bingol in southeastern Turkey. One person was killed during the raid.
Tensions have been running high ahead of the Sunday elections as the ruling Justice and Development Party (AKP) is trying to bring more lawmakers into Turkey’s legislative chamber to succeed in making its long-promised changes in the country’s constitution. That would mean an upper hand in almost all administrative and security issues for incumbent President Recep Tayyip Erdoğan.
Erdoğan’s aspirations could be seriously hampered, however, as the HDP has vowed to block the move if it wins more than 10 percent of the total votes required to take seats in the parliament.
