Israeli troops have killed three suspected Palestinian militants in the West Bank.

Witnesses say Israeli forces entered the town of Nablus Thursday and opened fire on a building where militants were believed to be hiding. Israel says its troops were searching for wanted militants, and shot the three men as they tried to flee.

Hours later, militants in the Gaza Strip fired a rocket into an Israeli military base, injuring five soldiers. Israeli military officials say troops responded with artillery fire at fields used by militants to launch rockets at Israel. Palestinian medical officials say a Palestinian man was killed in the strike.

Separately, an Israeli court Thursday sentenced an Israeli woman to three years in prison after she pleaded guilty to collaborating with Palestinian militants.
