ANKARA, Turkey — Turkish warplanes struck Islamic State group targets across the border in Syria on Friday, government officials said, a day after IS militants fired at a Turkish military outpost, killing a soldier.
The bombing is a strong tactical shift for Turkey which had long been reluctant to join the U.S.-led coalition against the extremist group.
A government official said three F-16 jets took off from Diyarbakir airbase in southeast Turkey early Friday and used smart bombs to hit three IS targets across the Turkish border province of Kilis. The official, who spoke on condition of anonymity because of government rules requiring authorization for comment, said the targets were two command centers and a gathering point of IS supporters.
The private Dogan news agency said as many as 35 IS militants were killed in the airstrike that targeted the gathering point. The agency did not cite a source for the report and there was no official confirmation.
A government statement said the decision for the operation was taken at a security meeting on Thursday, held after five IS militants fired from Syrian territory at the outpost and prompting Turkish retaliation that killed at least one IS militant.
The official said the Turkish planes did not violate Syrian airspace.
The bombing followed a decision by Turkey this week to allow the U.S. military to use the key Incirlik air base near the border with Syria to launch airstrikes against the Islamic State, senior U.S. officials said.
Turkey has yet to publicly confirm the agreement, which U.S. officials discussed on condition of anonymity because they weren't authorized to comment publicly. Citing operational security, the White House declined to confirm the agreement, but noted that Obama and Turkish President Recep Tayyip Erdogan had agreed to "deepen our cooperation" against IS in their phone call Wednesday.
The agreement follows months of U.S. appeals to Turkey and delicate negotiations over the use of Incirlik and other bases by the U.S.-led coalition — a sensitive topic in Turkey.
American officials said access to the base in southern Turkey would allow the U.S. to move more swiftly and nimbly to attack IS targets.
On Friday, Turkish police launched a major operation against terror groups including IS, carrying out simultaneous raids in Istanbul and 12 provinces and detaining more than 250 people, a government statement said. The state-run Anadolu Agency said as many as 5,000 police officers were involved in the operation which was also targeting the PKK Kurdish rebel group and the outlawed far-left group, DHKP-C.
One DHKP-C suspect, a woman, was killed in a gunfight with police in Istanbul, Anadolu reported.
Turkey's moves came as the country finds itself drawn further into the conflict by a series of deadly attacks and signs of increased IS activity inside the country.
Earlier in the week, a suicide bombing blamed on IS militants killed 32 people in a town near the Syrian border.
Turkish officials have raised concerns that the bombing was part of a campaign of retaliation for Turkey's recent crackdown on IS operations in the country. In the last six months, Turkish officials say, more than 500 people suspected of working with IS have been detained.
