GAZA, May 25 (Reuters) - Israeli helicopter gunships destroyed a caravan used to house bodyguards of Palestinian Prime Minister Ismail Haniyeh when they fired three missiles on targets in the northern Gaza Strip on Friday, witnesses said.

Hospital officials said a passerby was wounded in one strike on a home in the Jabalya refugee camp. Another missile destroyed a caravan used to house Haniyeh's bodyguards near his home in Gaza City, but no one was hurt, witnesses said.

The Israeli military had no immediate comment.

Israel's air force struck near Haniyeh's home earlier on Friday, but military official said he was not the target.

Haniyeh is a top member of the governing Islamist group Hamas, whose armed wing has stepped up rocket attacks on Israel from Gaza in recent days.
