GAZA CITY, Gaza Strip — Israeli troops shot dead a Palestinian man and wounded 19 people as crowds surged toward Gaza's border fence with Israel on Friday, a health official said, the first violence since a truce between Israel and Gaza's Hamas rulers took hold a day before.

The shooting did not appear to pose an immediate threat to the Egypt-brokered cease-fire, which called for an end to Gaza rocket fire on Israel and Israeli airstrikes on Gaza. The truce came after eight days of cross-border fighting, the bloodiest between Israel and Hamas in four years.

The Gaza prime minister, Ismail Haniyeh of Hamas, has urged militant factions to respect the cease-fire. It appeared unlikely Hamas would retaliate for the Friday's shooting because that could jeopardize the militant group's potential gains from the cease-fire deal, such as an easing of restrictions on movement in and out of the Palestinian territory.
