Three Palestinians were killed and several others injured Monday when Israel blew up a tunnel stretching from the Gaza Strip into its territory, the health ministry in the Hamas-run enclave said.

Ahmed Abu Armanah, Omar al-Faleet and Misbah Shubir were killed in the explosion, health ministry spokesman Ashraf al-Qudra said in a statement.

Shubir was from Hamas's armed wing, the group said, while the other two were believed to be from an allied militant group.
