Israeli troops kill two gunmen in Gaza

(Adds clash, one killed)

GAZA, March 28 (Reuters) - Israeli troops killed two Palestinian gunmen and wounded two others on Friday during clashes in the Hamas-controlled Gaza Strip, the Islamist group and the army said.

An Israeli army spokesman said troops shot a gunman in the northern part of the territory after he hurled a grenade at them near the border fence with Israel. The spokesman said the gunman appeared to have been killed.

Medical officials in the territory said the army informed them of casualties, but warned not to approach the area.

Earlier on Friday, troops opened fire on a group of gunmen during an incursion into the southern Gaza Strip, killing one and wounding two others.

Israel regularly raids the coastal enclave in what it says is an attempt to curb cross-border rocket attacks by Palestinian militants into Israeli towns.

Hamas seized control of the Gaza Strip in June after routing Palestinian President Mahmoud Abbas's Fatah forces. (Reporting by Nidal al-Mughrabi; writing by Joseph Nasr; editing by Richard Williams)
