'Upping the ante'
The strikes were carried out in response to the killing of a Jordanian fighter pilot by IS militants.
A video of Moaz al-Kasasbeh being burned alive in a cage was posted online by IS earlier this week.
He was captured by the militants in December after his F-16 fighter jet crashed in Syria. The video is believed to have been filmed on 3 January.
Foreign Minister Nasser Judeh said Thursday's strikes were "the beginning of our retaliation" against IS.
"We're upping the ante. We're going after them wherever they are, with everything that we have," he said.
Thousands rallied in Jordan's capital, Amman, on Friday morning in support of their government's military response.
Among those marching was Jordan's Queen Rania who told the BBC the country was "united in our horror".
She said Lt Kasasbeh's killing had made Jordanians "determined to rid the world of this evil".
