The commander of the Incirlik air base in southern Turkey that is used by the US military and its allies is among the 6,000 members of Turkey's military and judiciary to have been detained by the government.

The government is accusing General Bekir Ercan Van of complicity in last week's coup attempt that, so far, has left more than 260 people dead.

In addition, 10 soldiers, including one officer, at the base have also been arrested.

The air base, which is used by US and allied jets to launch strikes against "Islamic State" (IS) militants in Syria and Iraq, was shut down Saturday. Late Sunday the Pentagon announced it had resumed operations at the base.

"After close coordination with our Turkish allies, they have reopened their airspace to military aircraft," Pentagon spokesman Peter Cook said in a statement.

"As a result, counter-ISIL coalition air operations at all air bases in Turkey have resumed," he added, using another acronym for IS.

Erdogan: "Continue cleaning 'virus' from state institutions"

Turkish President Recep Tayyip Erdogan vowed on Sunday to clean out the "virus" within the state bureaucracy. His promise came during a speech at the funeral of victims killed during the coup attempt.

"We will continue to clean the virus from all state bodies because this virus has spread," he warned mourners at a mosque in Istanbul. "Unfortunately like a cancer, this virus has enveloped the state. We knew this and told all relevant authorities."

Erdogan accuses US preacher

Erdogan repeatedly criticized his enemy Fethullah Gulen, a US-based preacher who he accuses of being behind the attempted coup.

"They have nowhere to flee," Erdogan said, urging his supporters to continue to occupy public places and take to the streets in the days ahead.

Gulen denies having any connection to the coup.

"As someone who suffered under multiple military coups during the past five decades, it is especially insulting to be accused of having any link to such an attempt," Gulen said in a statement. "I categorically deny such accusations."

Erdogan is demanding the US extradite Gulen, but Washington says it will only do so if given concrete evidence against the preacher.

Meanwhile, the US and its allies are cautioning Erdogan not to overreach in his post-coup crackdown.

"We have urged them not to reach out so far that they are creating doubts about their commitment to the democratic process," US Secretary of State John Kerry said during a Sunday morning news program broadcast in America.

Kerry said he had no evidence that Gulen was behind the coup, but urged Turkey to provide any such evidence as soon as possible.
