ANKARA - Turkey has shut its side of the last border crossing with Syria still controlled by Syrian President Bashar Assad's government, stepping up security following two deadly bombings this month.
Fifty-one people were killed when twin car bombs ripped through the Turkish border town of Reyhanli in the southern province of Hatay on May 11, heightening fears that Syria's civil war was dragging in neighboring states.
Turkey has accused Syria of involvement in the attacks. Damascus has denied any role.
Customs Minister Hayat Yazici said the Yayladagi gate, some 90 km (55 miles) from Reyhanli, would remain closed for a month, during which only Turkish citizens arriving from Syria or non-Syrians transiting through Turkey would be allowed to cross.
Nobody would be allowed to cross from Turkey into Syria.
