A show of unity: Can Turkey's failed coup unite the country?

Turkish authorities are saying at least 10 foreign nationals are facing legal action because they're suspected of ties to a US-based cleric, Fethullah Gulen, who Turkey accuses of masterminding last month's coup. The news comes a day after at least one million people turned up to a rally in support of the president. But not everybody was invited: The third largest party in parliament, the pro-Kurdish HDP, was not on the guest list. So just how unified is Turkey in the wake of the coup attempt?
