(Adds new strikes, army statement, updates wounded)

GAZA, Feb 6 (Reuters) - An Israeli missile strike wounded three Palestinian militants in the northern Gaza Strip on Wednesday as they tried to launch makeshift rockets into Israel, Hamas and medical officials said.

An Israeli army spokesman confirmed the strike on Palestinian gunmen near the northern Gaza town of Beit Hanoun.

Earlier, four civilians were wounded by two air strikes on an unoccupied metal foundry and a caravan that was located outside a Hamas security position, the officials said.

The spokesman said the army carried out two attacks on a weapons depot and a weapons manufacturing facility in the central Gaza Strip.

Israel frequently carries out strikes against Gaza militants to try to stop them from launching rockets and mortar shells across the border into nearby towns in the Jewish state.
