TEHRAN, April 7 (Xinhua) -- At least two people were killed and three others injured as a railway bridge in Iran's central province of Isfahan was attacked Tuesday by the United States and Israel, the official news agency IRNA reported.

The bridge is located in Yahyaabad village in Kashan County, the IRNA quoted Akbar Salehi, Isfahan's deputy governor for political and security affairs, as saying.

According to the IRNA, an area near Kashan's train station was also targeted with three projectiles at around 13:00 local time (0930 GMT), damaging a number of nearby residential units as well as cars.

Meanwhile, the semi-official Tasnim news agency reported that a number of road bridges west of Iran's central Qom province were also struck by U.S. and Israeli projectiles on Tuesday, without causing any casualties.

According to Iran's semi-official Mehr news agency, several explosions were heard in Iran's Kharg Island on Tuesday, following multiple attacks by the United States and Israel.

Western media reports said the attacks hit over 50 military targets on the island, which is Iran's oil export hub.

Also on Tuesday, Iran's Islamic Revolution Guard Corps (IRGC) said it has targeted an Israeli-owned container ship trying to transfer military equipment to Israel through the United Arab Emirates without crossing the Strait of Hormuz.

Additionally, the IRGC warned that if the U.S. army crosses the red line in attacking civilian targets, Iran's response "will go beyond the region," stressing, "We have not been and will not be the initiators of attacks on civilian targets, but we will not hesitate to retaliate vile aggressions against civilian facilities."

U.S. President Donald Trump previously threatened to strike and destroy bridges and power plants across Iran.

The developments came amid heightened regional tensions following joint U.S.-Israeli strikes on Iran starting on Feb. 28, to which Iran and its regional allies responded with attacks on Israeli and U.S. interests across the Middle East. ■
