AMMAN, Jordan (AP) — Jordan’s Foreign Minister said the kingdom has taken precautions to ward off a possible Syrian chemical attack.

Nasser Judeh said “the matter is of grave concern to us, and we have taken all necessary measures to confront that.” He declined to say what measures were taken.

“We will not allow anything to threaten the internal security of the kingdom,” he told reporters Tuesday at a joint news conference with visiting British Foreign Minister William Hague.

Israel and others have expressed concern about Syrian chemical weapons. Syria does not comment on the subject.

Despite threats in 1970 and 1982, Syria has never attacked Jordan.

Syria opposes Jordan’s alliance with the United States and its peace treaty with Israel, but Jordan is hesitant to rile Syria, its powerful neighbor.
