Israeli troops wounded in West Bank bus shooting

STORY: The incident, in which authorities said two suspected gunmen were detained as they tried to escape, took place within driving distance of Jenin and Nablus, Palestinian cities that have seen months of intensive and often lethal Israeli security sweeps.

Witnesses said Palestinians in a car overtook the bus, spraying it with bullets and, when it came to a halt, tried to torch it.

There was no immediate Palestinian claim of responsibility, but a spokesman for Islamist Hamas praised the attack as "proof that all attempts by the Occupation (Israel) to stop the escalating resistance operations in the West Bank have failed."

Israel has stepped up raids in the West Bank over recent months after several deadly attacks by Palestinians in its cities between March and May.
