Armed violence is the most used instrument of power for organizations such as the Kurdistan Workers Party (PKK) to impose their political agendas. But in recent months there have been signs that the PKK is having trouble managing this violence. The latest example came May 10 in the Durumlu village of Turkey's Diyarbakir’s Sur district, when a massive explosion killed 16 civilians.

According to villagers' statements, Orhan Yakar noticed a suspicious truck that night near his house. Yakar, who has been wary of recent animal thefts, asked the driver his identity and why he was in Durumlu. Yakar was not satisfied with the driver’s responses and began arguing with him, but the driver pulled out his pistol and warned Yakar to go away. Yakar went to his house to get his own weapon and called on his relatives to help him. As the truck was driving away, villagers pursued it in several vehicles.

Village head Bayram Yaman said the villagers did not know who was in the truck or its cargo. Just as they stopped the truck, there was a massive explosion. The blast left a crater 30 meters (almost 100 feet) wide and 4 meters (13 feet) deep. Three bodies were recovered, but 13 villagers were initially listed as missing and later identified as dead. Dozens of residents were wounded. The size of the crater suggested the explosive was nitrate based and enhanced with 10-12 tons of C3, a plastic explosive.

The PKK’s military wing, the People’s Defense Forces, issued a written statement claiming that the truck, which had been loaded with explosives by PKK militants, was stopped by some local people while driving away and exploded because of bullets that hit in the ensuing clash.
