Iran's President Hassan Rouhani has pledged that the Islamic republic is "too great to be intimidated by anyone", as tensions rise with the United States.
"God willing we will pass this difficult period with glory and our heads held high, and defeat the enemy," he said at a meeting with Sunni clerics late Monday, government website dolat.ir reported.
He was speaking after four ships, including two Saudi oil tankers, were reportedly attacked off the UAE coast Sunday, amid mounting regional tensions.
Iran has called for an investigation into what it called an "alarming" incident.
On Tuesday, a senior member of Iran's parliament blamed Israel for the attacks on shipping for which there has been no claim of responsibility.
The attacks "appeared to be Israeli mischief", Behrouz Nemati said after a closed-door session of parliament, quoted by state news agency IRNA.
Tehran and Washington have engaged in a war of words since Iran began to roll back commitments set out in a 2015 nuclear deal with world powers.
US President Donald Trump withdrew from the deal last year and has unilaterally reimposed stringent sanctions on Iran.
Washington's dispatch of the USS Abraham Lincoln carrier group, an amphibious assault ship, a Patriot missile battery and B-52 bombers to the region has sparked fears of possible military clashes.
