Two powerful car bombs killed at least 43 people in a town near Turkey’s border with Syria on Saturday in one of the deadliest attacks on Turkish soil in at least a decade, with Ankara vowing to bring the perpetrators to justice.

Rescuers have begun the search for possible survivors buried underneath the rubble of buildings destroyed by the blasts on Saturday in Reyhanli, one of the main Turkish hubs for Syrian refugees and militiamen.

Deputy Prime Minister Besir Atalay confirmed that the twin blasts had killed at least 43 people and wounded 100 more, many of whom were said to be in critical condition.

There were no immediate claims of responsibility for the attacks, which came 15 minutes and barely a mile apart. Hours later, Turkish officials, including Interior Minister Moammar Guler, blamed the attack on an organization linked to Syria’s intelligence services, though they did not name the organization or the suspects, or provide a detailed explanation of how they reached that conclusion.

Atalay said the perpetrators of Saturday's attacks did not appear to have crossed into Turkey from Syria but were already in the country.

One of the bombs left a crater by Reyhanli’s yellow municipal headquarters, blasting out its windows and leaving files on aluminum shelves visible from the street. A nearby row of buildings, where apartments sat above stores, was destroyed.

The second bomb appeared to have been far more powerful, sheering the facade off office towers in downtown Reyhanli and sending the burned shells of cars and motorcycles crashing into stores.

After the bombings on Saturday, angry residents smashed the windows of cars from Syria, and a Turkish newspaper reported that protests against Prime Minister Recep Tayyip Erdogan later erupted in Reyhanli’s streets.

Turkish Foreign Minister Ahmet Davutoglu, on a visit to Berlin, said it was "not a coincidence" that the bombings occurred as international diplomatic efforts to solve the Syrian crisis were intensifying.

The attack on Saturday occurred as Erdogan was scheduled to visit Washington this week to meet US President Barack Obama and discuss the urgency for a resolution of the conflict in Syria. Secretary of State John Kerry released a statement condemning the bombings and praising Turkey’s role as a “vital interlocutor.”

Erdogan also made a reference to the conflict in Syria, and raised the possibility that the attack was linked to his government’s talks with the P.K.K., the Kurdish separatist group, to end three decades of armed conflict.

The United States and Russia pledged this week to relaunch efforts to solve the conflict, which the United Nations estimates has killed 70,000 people since March 2011.

Around Reyhanli, some 25,000 Syrian refugees live among 90,000 Turkish citizens, according to local officials.
