The death toll from a coal mine explosion in Iran has risen to 42 after search crews found seven more bodies at the site of the blast.
Rouhani, the moderate cleric seeking re-election May 19, "insisted" on traveling to northern Golestan province to review the disaster and speak with the families of those who died, the official Islamic Republic News Agency said.
President Hassan Rouhani's auto came under attack from angry miners and the families of victims when he visited the site on Monday.
Coal miners and rescue workers gather at the scene following the explosion in a coal mine in Azadshah.
Several officials blamed the explosion on an accumulation of methane gas and said it was affecting rescue efforts.
In a rare protest targeting the nation's top elected official, the miners - some covered in coal soot from searching for fallen comrades still missing - began kicking and banging on the armoured SUV carrying Mr Rouhani.
Local news agencies showed people stamping on Rouhani s vehicle and beating the windows as it tried to make its way through an angry crowd at the site in the northern Golestan province, where at least 26 people were killed by an explosion on Wednesday.
"[As government] we are responsible for their lives and it is our duty", the president said.
Iran, primarily thought of for its oil reserves, is also rich in minerals.
His conservative rivals for the presidency have accused him of failing to revive Iran's economy following the country's landmark nuclear deal with world powers. "Those who are guilty in this incident should be prosecuted by a court". Iran annually consumes some 2.5 tons of coal but only extracts about 1 million tons from its mines per year.
Iran's first Vice-President Eshaq Jahangiri has directed the concerned departments to speed up the rescue operations. He ordered the shutdown of all mines across the country that lacked safety standards with immediate effect.
