GAZA, October 26 (RIA Novosti) - At least six Palestinian gunmen were killed and a dozen wounded in Israeli air strikes and troops clashes in Gaza, Palestinian radio said Friday.

Four Palestinians died in an air strike in east Gaza, one was shot dead in south Gaza, and the other was killed in the north in an exchange of fire with Israeli troops, two of which were slightly wounded.

Three of those killed on Friday were members of the Islamic Jihad movement, and the others were part of radical Islamist group Hamas, which has controlled the Gaza Strip since June.

In September, Israel declared the Gaza Strip, with a population of 1.5 million, an "enemy entity," and warned it could launch a large-scale military operation in the enclave, complicating plans for a U.S.-proposed Middle East conference scheduled for November.

Along with air strikes and raids Israel intends to impose economic sanctions, including cutting electricity and fuel supplies to the Gaza Strip, where militants continue to fire mortars and rockets at Israel.
