Gunmen from Palestinian Fatah movement and the Islamic Resistance Movement (Hamas) clashed in the Gaza Strip on Friday, wounding at least two people, witnesses said.

Gunmen from Fatah and Hamas exchanged fire near the city of Khan Younis in southern Gaza, one day after Hamas defeated Fatah in the Palestinian parliamentary elections with a landslide victory, the witnesses said.

It was the first clash between the two rival groups since Wednesday's elections.

Hamas, a radical militant group which shunned the first Palestinian parliamentary elections in 1996, made a shocking win in its first legislative bid with an overwhelming claim of 76 seats against the previously dominant Fatah which gained only 43 seats, according to the official results announced on Thursday.

Fatah, which has been a ruling movement in the past four decades, is currently led by Palestinian President Mahmoud Abbas.

A senior Hamas leader on Friday called for talks with Abbas within two days in Gaza about the formation of a new cabinet.
