ISTANBUL (AP) — Opposition Cumhuriyet newspaper says a court has ordered that its chief editor and eight senior staff be jailed pending trial.

Editor-in-chief Murat Sabuncu, cartoonist Musa Kart and other staff were detained for questioning earlier this week — some following raids at their homes — for allegedly supporting Kurdish militants as well as a movement led by Fethullah Gulen, the U.S.-based Muslim cleric whom Turkey accuses of masterminding the failed coup in July.

The court ruled for their formal arrests on Saturday.

Their detentions came amid a widening government crackdown on opposition voices. On Friday, authorities arrested the two co-chairs of Turkey's pro-Kurdish political party and several other party lawmakers for alleged ties to Kurdish militants.

Turkey's Western allies have voiced concern over the clampdown on Cumhuriyet and the pro-Kurdish party.
