Israeli fire into the Gaza Strip killed a Palestinian on Tuesday, medical workers said, despite the separetly 10-day ceasefire by Hamas and Israel.
One Israeli soldier was killed and three wounded in a blast near the border with Gaza, Al Arabiya television reported earlier in the day.
It is the first apparent breach of a January 18 ceasefire between Israel and Hamas, which controls the Gaza Strip.
The Palestinian, identified by the medical workers as a farmer, was killed after Israeli forces fired into an area about a kilometre (half-mile) from the site where Al Arabiya television said the soldier was killed and three other troops were wounded.
It gave no other details. The Israeli military had no immediate comment.
Israel launched on December 27 a massive offensive in Gaza, killing more than 1,300 Palestinians, a third of them children, and wounded 5,300 Palestinians.
Israel destroyed Gaza infrastructure, suffering massive damage totaling some 476 million dollars, according to Palestinian medics and officials.
Gazans live under heavy Israel siege for a long time and Egypt still insists on not to opening the only Gaza border crossing in a move condemned by Muslims around the world in protests, leaving Gazans desperate to digging tunnels underground and risking their lives.
