Israeli forces on Tuesday killed two Hamas militants in exchanges of fire during a brief army incursion in the Islamists-ruled Gaza Strip, Palestinian medical sources said.
The gunbattle erupted after several Israeli armoured vehicles and tanks crossed several hundreds of metres east of the town of Bir el-Balah in central Gaza, the sources said.
Two members of Hamas's armed wing, identified as Abdullah Louh and Yehya Borrak, were killed in the exchanges of fire, that came as both sides have observed a relative lull in violence in and around Gaza for three weeks.
Two civilians were also injured in the same incident, the sources said.
An Israeli army spokeswoman confirmed that troops "indentified and hit" two gunmen during the incursion. Several other Palestinians were detained for questioning, she added.
Late on Monday, Palestinian militants fired two rockets against southern Israel, causing no casualties or damage.
Tuesday's deaths bring to 363 the number of people killed since Israelis and Palestinians revived their peace talks at a US conference last November after a seven-year hiatus, according to an AFP count.
At least 6,326 people have been killed since the start of the second Palestinian uprising in September 2000, the vast majority of them Palestinians, according to a separate AFP tally.
