Deputy Hamas politiburo head Dr. Mousa Abu Marzouk has threatened Israel over its decision to close Gaza's border crossings Sunday, stating to Hamas news agency Al Risala that the move will not be quietly overlooked. 

"This is a childish and irresponsible act," Marzouk fired. "This is collective punishment on the Gaza Strip which violates all international laws, including the terms of the ceasefire agreement." 

"This will not be quietly overlooked," he continued. 

Israel announced on Saturday night that the Kerem Shalom and Erez crossings into Gaza will be closed on Sunday, following Friday night’s rocket attack on the Eshkol region.

The crossings will only be opened for passage of goods and people in humanitarian cases, according to the announcement.

The Coordinator of Government Activities in Judea, Samaria and Gaza informed the Palestinian Authority of Israel’s decision. This is the first time that Israel has closed the crossings to Gaza since Operation Protective Edge last summer.

Friday’s incident marked the second time since the end of Operation Protective Edge that Gaza terrorists have attempted rocket fire towards Israel.

Last month, a mortar attack was launched by Gazan terrorists against southern Israel, in breach of a ceasefire signed in August. Hamas, which breached numerous ceasefires during the operation, denied responsibility for the attack and later announced it had arrested the perpetrators.
