ANKARA, Turkey — A bomb attack targeting an outdoor wedding party in southeastern Turkey on Saturday killed at least 22 people and wounded 94 others, authorities said.

Deputy Prime Minister Mehmet Simsek said the “barbaric” attack in the city of Gaziantep, near the border with Syria, appeared to be a suicide bombing. Other officials said it could have been the carried out by either Kurdish militants or Islamic State group extremists.

Photos taken after the explosion showed several bodies covered with white sheets as a crowd gathered nearby.

Turkey has been rocked by a wave of attacks in the past year that have either been claimed by Kurdish militants linked to the outlawed Kurdistan Workers’ Party – known by its acronym PKK – or were blamed on the Islamic State group, also known as ISIS or ISIL. In June, suspected Islamic State militants attacked Istanbul’s main airport with guns and bombs, killing 44 people.

The attack comes as the country is still reeling from last month’s failed coup attempt, which the government has blamed on U.S.-based Muslim cleric Fethullah Gulen and his followers.

A brief statement from the Gaziantep governor’s office said the bomb attack on the wedding in the Sahinbey district occurred at 10:50 p.m. The statement condemned the “treacherous” attack, but did not provide further details.

In Gaziantep, police sealed off the site of the explosion and forensic teams moved in. Hundreds of residents gathered near the site chanting “Allah is great” as well as slogans denouncing terrorist attacks.
