BEIRUT - Israeli forces killed at least four people in the volatile city of Jenin in the occupied West Bank, medics said on Tuesday, following a night of violence in which four others were killed in clashes near Tubas, close to the border with Jordan.

The Israeli military said it conducted two separate air strikes in the West Bank, hitting armed militants, but gave no details.

The Palestinian Red Crescent confirmed that four people were killed in the strikes against two vehicles in Jenin, one of the most explosive flashpoints in the West Bank. Another person was critically wounded.

In southern Lebanon, an Israeli airstrike hit a house in the village of Maifadoun, killing four people, the National News Agency reported.

Lebanon's armed group Hezbollah announced that it launched drones on military targets in northern Israel on Tuesday.

Hezbollah said in a statement that it launched an air attack "with a squadron of suicide drones that targeted the headquarters of the Golani Brigade and the headquarters of the Egoz Unit 621 in the Shraga barracks north of occupied Acre."

Confrontations between Hezbollah and the Israeli army escalated following Israel's attack on Dahieh in Beirut's southern suburbs, killing Hezbollah senior military commander Fouad Shokor and seven civilians. Hezbollah Secretary-General Hassan Nasrallah threatened a definite and painful response to the Israeli raid at the appropriate time and place.

The strikes in the West Bank came during an operation in Jenin in which footage shared on social media showed a column of armored personnel carriers entering the city and armored bulldozers digging up roads.

With Israel bracing for an expected Iranian response to the assassination of Hamas leader Ismail Haniyeh in Teheran last week, the West Bank violence underscored the multi-front security challenge facing Israeli forces, 10 months after the start of the war in Gaza.

Israeli forces have killed hundreds of Palestinians in the West Bank and East Jerusalem since the start of the war, many of them armed fighters but many also stone-throwing youths or uninvolved civilians.

At the same time, at least 13 Israelis have been killed in attacks by Palestinian attackers. On Tuesday, a female border guard was wounded in a stabbing attack by a Palestinian man using a screwdriver during an inspection of a bus at a chackpoint on the outskirts of Jerusalem.

Body bags were laid out for a mass burial in Gaza on Monday, after Israel returned 80 bodies it had previously taken from various graves and locations across the strip.

The attacker was shot dead, the police said.

Overnight, the Palestinian health ministry said at least four Palestinians were killed and seven others injured by Israeli fire in the town of Aqaba, close to the city of Tubas.

Two of the injured were in critical condition.

The official Palestinian news agency WAFA said the clashes occurred after Israeli forces surrounded a house in Aqaba and clashed with a group of young men.
