DUBAI, May 10 (Reuters) - Gulf markets were mostly weak in early trade on Thursday amid investor concerns over an escalation of tensions in the Middle East, where Israel responded to what it said was a rocket attack from Iranian forces in Syria.
The attack on the Israeli-occupied Golan Heights, just after midnight, marked the first time Iranian forces have attacked Israel from Syria, where they have deployed along with Iran-backed Shi'ite militias and Russian troops to support President Bashar al-Assad in Syria's civil war.
